I found lots of duplicates of this exact bug in spread, all with pretty much the same stack trace, which have been marked as duplicates of this bug.
Additionally, many crashers with the similar stack traces and the *same* assertion failure in XLib during the normal event loop handling have been reported against the dash too, and are marked as duplicates of Bug 745964 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/747648 Title: [spread] crashes in event loop -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
