evince segfaults

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please try to obtain a backtrace following the instructions at http://wiki.ubuntu.com/DebuggingProgramCrash and upload the backtrace (as an attachment) to the bug report. This will greatly help us in tracking down your problem.

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

I have done some testing.
The problem is not Evince nor the package libgrip0.
The bug is in the package libutouch-geis1_2.2.0-0ubuntu1

Workaround:
Downgrade to the earlier libutouch-geis1 version 2.1.2-0ubuntu4.

This bug was fixed in the package utouch-geis - 2.2.1-0ubuntu1

---------------
utouch-geis (2.2.1-0ubuntu1) precise; urgency=low

  * New upstream release.
  * Remove all callbacks and filters on DBus client shutdown (LP: #879348).

This bug is certainly not fixed with the libutouch-geis1, version 2.2.1-0ubuntu1.
Evince does segfault with this update exactly the same way as with the version 2.2.0-0ubntu1.
So, it is of no use for Evince.
The only working version is 2.1.2-0ubuntu4.

I can confirm 2.2.1-0ubuntu1 doesn't solve the problem and evince/eog are still freezing for me here.
2.1.2-0ubuntu4 works though.

Note this happens using Xserver 1.11.

Reopening since the bug doesn't seem fixed.

It seems clear to me that the libutouch-geis1_2.2.1-0ubuntu1 does not work with xserver 1.11 series.
This is because xserver 1.11 does not have utouch support yet and libutouch-geis1_2.2.1-0ubuntu1 cannot handle that.
This is why evince segfaults.

I am unable to reproduce either the crash or the hang in Precise. In the case of the crash, please try to obtain a backtrace following the instructions at http://wiki.ubuntu.com/DebuggingProgramCrash and upload the backtrace (as an attachment) to the bug report. This will greatly help me in tracking down your problem.

For slightly more detail, evince it sitting on this system call:

select(12, [0 11], NULL, NULL, NULL) = 1 (in [0])

Where 0 is stdin and 11 is from "epoll_create1(O_CLOEXEC)" and listed as "anon_inode:[eventpoll]". Hitting any key will cause the select to spin.

btw, eog is also effected.

This is due to the xorg-edgers ppa xserver-xorg-input-evdev module not having utouch support. The utouch library response when confronted with this is to just hang.

That's a really bad response to an error. Please, Please, Please. If you can't connect, just don't give utouch support, or at the very least provide a GEIS_DISABLE env.

Currently only evince and eog are broken, but they are rather critical apps.

The response of the uTouch stack to an S server that does not support the gesture protocol is not to hang but to report the error and fail gracefully. That has been fully tested over many releases.

All of the stack traces that have been posted show that utouch-geis is hanging while trying to connect to the session dBus server to query for the existence of a uTouch service. This occurs long before any attempt is made to contact the X server for any reason. It is unclear why the dBus library does not handle this case in an expected manner on some precise installs and not others, since it works on all this developer's precise installs.

Investigation is continuing.

(I'm running precise, but with the xorg edgers ppa)

Since an application hanging is an entirely different bug than the crash originall reported here, I have taken the liberty of opening an entirely new bug for that complaint. Please redirect all follow-up correspondance not dealing with the original crash bug to bug #898175.

This was likely fixed in a previous version of utouch-geis. I am marking this bug as fix released. If it is not, please reopen.
