gtk-logout-helper crashed with SIGABRT in __libc_start_main()

Last night I did a partial distribution update using Update Manager. Then I switched this computer off.
When I switched this computer on this morning, I obtained the above error message.

Happened to me after cold but on a freshly installed daily live built on a usb stick (version 19-Apr-2011). Have been trying daily builds frequently, this is the first time it hapened to me...

This happened after I installed 11.04 to a 16GB Toshiba USB stick, and booted the stick - about 30 seconds after the Unity Desktop came up. I hadn't tried doing a thing yet with the mouse or keyboard.

Please note: since an update to 10.04 Lucid, I've been unable to get preboot and boot screens, and no amount of fiddling with grub2 made any difference. The screen does come on after the default kernel is loaded, but not at the proper resolution (16:10) for my wide screen, which leaves fat vertical black stripes on either side of the screen.

My BIOS is the original version, and needs updating (all the drivers too) - but I can't do the flash when the black screen prevents me from getting into Windows and/or BIOS. Live CDs also show no screen, (Even Windows XP), so the boot fails waiting for my input. This is a show-stopper for me.

I wonder if this new bug is related to the firmware problems I just described.

Laptop: Acer Aspire 5602WLMi
graphics: Intel GMA 950
chipset: 945GM

So, at some level this has to be an invalid read, but I can't figure out where. Could someone who gets this regularly please run the gtk-logout-helper under valgrind?

https://wiki.ubuntu.com/Valgrind

The command you need to run is: valgrind /usr/lib/indicator-session/gtk-logout-helper --shutdown

Thanks!

Here ya go!

@jml, thanks! That doesn't seem to be showing the bug though :-/ Anyone able to recreate it regularly?

after update, then crash

My Valgrind log.

I am affected with the latest kernel.

Description: Ubuntu oneiric (development branch)
Release: 11.10

Hello,

We're having a difficult time tracking this bug down, so we're at the
point of looking for more information. Yesterday we released a new
version of indicator-session that should be in your local archive soon.
It is version 0.3.5. If those who are effected by these bugs could
ensure that they have this version:

  $ apt-cache policy indicator-session

and then run this:

  $ /usr/lib/indicator-session/gtk-logout-helper --shutdown &>
gtk-logout.log

And then attach that log to this bug that'd be really helpful. Thanks a
lot! Hopefully we can nail this soon.

  --Ted

Just did a apt-get update, apt-get upgraded and then apt-cache policy indicator-session, and got this:

indicator-session:
  Instalados: 0.3.4.3-0ubuntu1
  Candidato: 0.3.4.3-0ubuntu1
  Tabla de versión:
 *** 0.3.4.3-0ubuntu1 0
        500 http://mx.archive.ubuntu.com/ubuntu/ oneiric/main amd64 Packages
        100 /var/lib/dpkg/status

Why isn't version 0.3.5 in my Ubuntu box yet?

I just upgraded and also got:

indicator-session:
  Installeret: 0.3.4.3-0ubuntu1
  Kandidat: 0.3.4.3-0ubuntu1
  Versionstabel:
 *** 0.3.4.3-0ubuntu1 0
        500 http://archive.ubuntu.com/ubuntu/ oneiric/main amd64 Packages
        100 /var/lib/dpkg/status

Ted,

Today I applied an upgrade but the version of indicator-session is still
0.3.4.3. Once I get the 0.3.5 I send the log.

Edson.

I don't have this crash any more with 0.3.5
Also:
When logged in an ubuntu session there is no more lightdm-user session in parallel but only:
root lightdm
  \ myuser gnome-session

Ted,
As you requested, the logfile is there.

Att.
Edson.

It hadn't crashed for a while, until after today's kernel update.

Thanks guys. Hmm, so both of those logs aren't going through the code path that is in the stacktrace :-/ Anyone else able to get a log and a crash?

I don't get this crash anymore with new version.

got this bug while whole system was upto date

Updated today, got the crash a few minutes after login. There was a desktop without unity-panel, it did not appear on the screen but this error.

I'm getting this crash while running gnome-shell, which I find a bit strange.

is bug #852343 the same issue?

I am getting this crash consistently upon log in again.
Any suggestions on how to get the debugging information you requested?

Yes if you run the command from the terminal it should provide it. So like this:

  $ /usr/lib/indicator-session/gtk-logout-helper --shutdown &> gtklogout.log

Then attach that file please.

I got it again - not consistently - but here's the log anyway

Just got the crash when using shutdown dialog in Unity Greeter.
Unfortunately, ubuntu-bug fails to unpack it, so I attach it as is.

Traceback (most recent call last):
  File "/usr/bin/apport-unpack", line 44, in <module>
    pr.load(open(report))
  File "/usr/lib/python2.7/dist-packages/problem_report.py", line 133, in load
    l = base64.b64decode(line)
  File "/usr/lib/python2.7/base64.py", line 76, in b64decode
    raise TypeError(msg)
TypeError: Incorrect padding

This bug was fixed in the package indicator-session - 0.3.6-0ubuntu1
