It affects lots of X programs, including Evolution, Firefox, various parts of Gnome, etc. I wouldn't say it's critical, but it seems pretty serious for affected users.

However, the symptoms seem different from those mentioned in the previous comments, and I have neither a stack trace nor a reproducible testcase. Comments welcome, and if you don't want to spam either bug, my email addy is authentic (and the same @gmail.com works too). In reply to comment #5: For a user like me, any bug that causes crashes, hangs, or dataloss, even sporadically, is critical stuff. Now maybe SuSE has a different definition. ;-) -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
