Running gAIM on any display besides :0 will cause it to bail out with an X error in short order. Sometimes it takes as long as five minutes, but it always crashes.
Please try the gaim-0.10.3-1 package available in rawhide. Unlike the ggv package, it will be in the regular distro (it's moving from Powertools). Let me know if this helps. Tim
I've had it running on :6 under VNC for half an hour now. It does seem to be fixed.
