Description of problem: Fedora 11's thunderbird-3.0-2.3.beta2.fc11.x86_64, invoked from a command line as "thunderbird -safe-mode", and then used normally, prints many messages of the form: (thunderbird-bin:5081): Gdk-CRITICAL **: gdk_x11_xatom_to_atom_for_display: assertion `xatom != None' failed Thunderbird also seg faults occasionally. The two facts may be related. I am using Thunderbird to access a remote INBOX via IMAP, and keep 'local' folders in the local file system. This is pretty standard, so I assume the messages are being triggered by some of the emails which I recieve. There is no obvious correspondence - I don't get one message per email received, or anything simple like that. The Gnome bugzilla claims to have a fix for what seems to be the same bug: http://bugzilla.gnome.org/show_bug.cgi?id=580511 So, it would be nice to have the fix come downstream, particularly if it really is what's causing my Thunderbird segfaults.
# COMMENT For me as well: thunderbird reacts extremely slow due to these errors. I also have my zimbra email account with lightning calendar of my account working there - they are loading in 10-15 minute with a high CPU load time and memory usage.
I also get this error: (thunderbird-bin:8483): Gdk-CRITICAL **: gdk_x11_xatom_to_atom_for_display: assertion `xatom != None' failed After this error appears ones CPU usage rises to 100% and thunderbird freezes. I can reproduce this behaviour all the time while trying to open one particular email from f-d: http://lists.grok.org.uk/pipermail/full-disclosure/2009-September/070675.html thunderbird version: thunderbird-3.0-2.6.b3.fc11.i586 gtk2: gtk2-2.16.5-1.fc11.i586 According to: https://bugzilla.gnome.org/show_bug.cgi?id=580511 this was fixed in 2.16.6
again, the error message is just noise. It doesn't change any behaviour. So whether you get it or not has no relation to whatever app misbehaviour you see.
I've just moved 2.16.6 to stable. Please reopen if you still see your problem with 2.216.6
