bluetooth-applet crashes when trying to browse device

Status changed to 'Confirmed' because the bug affects multiple users.

I can confirm the same under Oneiric and I believe I also experienced this under Natty, but I'm not certain about Natty as it has been a while. I'm adding a trace when using browse off the first menu (where the applet crashes) and a trace when using the device submenu and selecting browse. As an added bonus, this often causes my phone to shutdown or restart.

Thank you for your bug report, could you install gnome-bluetooth-dbgsym libgnome-bluetooth8-dbgsym (see https://wiki.ubuntu.com/DebuggingProgramCrash for details on how to do that) and get a new valgrind log? Could you also get the stacktrace using gdb or enable apport in /etc/default/apport and use it to send the bug?

Here's the log under the crash condition with the debug symbols installed.

Furthermore, here's the console output from the previously attached valgrind log session.

disappointing, the first time i want to use bluetooth on my computer and then it crashes ... :P

Dec 21 21:10:07 tavor kernel: [ 913.441246] bluetooth-apple[2842]: segfault at 80 ip 00007fef57b2bcf4 sp 00007fff09afa040 error 4 in libgnome-bluetooth.so.8.0.0[7fef57b1b000+1a000]

Here's a gdb stack trace from a crash I experienced.

The applet crash itself appears to be fixed in 12.04 with Gnome 3.2.1-1ubuntu3

Precise bug where a fix went in to take care of the tiny window, but, it also seems to take care of the segfaults:

Hi kent,

I can confirm that the patch in bug 829703, while making the window more presentable, doesn't actually fix the crash. I'll bisect the code tomorrow and find out what we can actually do to fix this.

Hi kent,

One of the variables was freed too many times. I think the only reason that this doesn't fail in precise is because the obex browse actually succeeds, and as a result the applet doesn't redisplay the dialog. In any case bluetooth-applet should be fixed to handle this failure case.

The crash can easily be fixed. Unfortunately, you still won't be able to browse devices until bug 879923 is fixed.

related to bug 899858 . If fixing that bug does not fix the problem we'll investigate a fix for the applet.

Fixing bug 899858 does not fix this bug. Interestingly, if the user selects the device itself and then selects browse, it works. It's just on first login when they select browse without the phone having been mounted before that this causes a problem.

If anyone is running precise and can test if this is still an issue I would appreciate commenting here.

I am running Precise, and this seems not to be an issue anymore. I just browsed my N9 via bluetooth, and it worked quite fine.

Likewise, resolved in 12.04

Still crashing in 12.10.

Marking it as won't fix, as the bug only shows when the rest of the bt stack does not work
