[Bug 738526] Re: Launching a Qt app crashes X with NVIDIA card even after fix for 650539
This is known upstream, the workaround is to not use xfs. ** Bug watch added: freedesktop.org Bugzilla #31501 http://bugs.freedesktop.org/show_bug.cgi?id=31501 ** Also affects: xorg-server via http://bugs.freedesktop.org/show_bug.cgi?id=31501 Importance: Unknown Status: Unknown ** Summary changed: - Launching a Qt app crashes X with NVIDIA card even after fix for 650539 + crash accessing font info with xfs in fontpath ** Changed in: xorg-server (Ubuntu) Status: Incomplete = Triaged ** Bug watch added: Debian Bug tracker #616578 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=616578 ** Also affects: xorg-server (Debian) via http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=616578 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/738526 Title: crash accessing font info with xfs in fontpath -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I'm experiencing an X crashing issue with Thunderbird, the computer it occurs on has an NVidia chip.

Thanks for collecting the gdb backtraces; in this case having several is very informative - the code crashes in different places each time, however it's the same routine, so presumably it's the same root cause. Since uninstalling xfs made it go away that makes me think xfs is corrupting the font structure at some point. Also thanks for listing possible dupe bugs. I've reviewed them and duped a couple, and commented on a couple others that look like they might be dupes but it's unclear. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/738526 Title: Launching a Qt app crashes X with NVIDIA card even after fix for 650539 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 738526] Re: Launching a Qt app crashes X with NVIDIA card even after fix for 650539
Ashely, if you're interested in debugging this particular issue further, here are some actions that could be taken: 1. Reproduce the issue and using gdb with a break set on doListFontsWithInfo and 'print c ' after the segfault to see what the contents of that structure is. This is to see if like in bug #683016 the c-num_fpes value is undefined. 2. Add a check in doListFontsWithInfo() to bail out early if c-fpe_list is NULL. I don't think that would be a proper fix, just paper over the issue, but it might be a good workaround for natty if it works. However if it does work it may simply move the bad behavior to somewhere else... 3. Test the current git version of xfs. There's been a couple changes to how font paths are done in xfs to match what xserver expects; perhaps that better avoids this situation. If you can't reproduce the crash when using this newer xfs, perhaps we simply need to update to newer xfs (or at least backport the font path patches). ** Changed in: xorg-server (Ubuntu) Importance: Undecided = Medium ** Changed in: xorg-server (Ubuntu) Status: New = Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/738526 Title: Launching a Qt app crashes X with NVIDIA card even after fix for 650539 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

That log file just shows a generic lockup, nothing actually usable for diagnosis. Please collect a full backtrace - see http://wiki.ubuntu.com/X/Backtracing for directions. Offhand, maybe it's an ABI incompatibility - those proprietary applications might need rebuilt against current X or something. ** Changed in: xorg-server (Ubuntu) Status: New = Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/738526 Title: Launching a Qt app crashes X with NVIDIA card even after fix for 650539 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
