I believe this crash happened as the spread was not being shut down cleanly. During logout, shell would hang around when the X server would shut down, making the display variable null, and hence causing XPending() to crash.
This issue has been fixed, shell shuts down properly when asked to by gnome-session. Therefore I'll mark this bug as fix released. Thanks for the update kriekse, and vibhavp for persuing it. -G ** Changed in: unity-2d Status: New => Fix Released ** Changed in: unity-2d (Ubuntu) Status: New => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/833603 Title: unity-2d-spread crashed with SIGSEGV in XPending() To manage notifications about this bug go to: https://bugs.launchpad.net/unity-2d/+bug/833603/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
