It looks like some kind of timing triggers it. I'm able to (sometimes) reproduce it when running ubuntu-bug, but not when running firefox directly.
I've tried to debug using strace, but I haven't been able to reproduce it using the -f option. Attached is output of strace -F -tt ubuntu-bug 2>strace-ubuntu-bug.log. I've not been able to reproduce it from gdb, the program always exits normally. ** Attachment added: "strace-ubuntu-bug.log" http://launchpadlibrarian.net/10047676/strace-ubuntu-bug.log -- Firefox crashes with BadWindow X error https://bugs.launchpad.net/bugs/97492 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
