For what it's worth, I just had this hit me again but on Fedora 11 with Firefox 3.5.8 on x86-64. Note: I don't have Flash on the system. The fact that it is Fedora should not be important since this is an upstream bug.
Removing the warning does not remove the bug, it just obscures it. If the flood of warnings is a problem, perhaps a patch to rate-limit the warning would be useful. Here's what I observed during this event: - FireFox opened a tab in a new window without the usual navigation bar etc. This is a sure sign that things have gone very wrong. - I looked in stdout from FF and it did have the dreaded XID warning - I closed the window that should have been a tab - firefox printed "firefox: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.0." on stdout and quit - No core file was produced even though I have the appropriate ulimit cranked up -- Gdk-WARNING **: XID collision, trouble ahead https://bugs.launchpad.net/bugs/401823 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
