Comment 1 Christophe Marin 2008-08-08 23:13:57 UTC 
This bug was already fixed and the fix will be part of 4.1.1.

Comment 3 Anne-Marie Mahfouf 2008-09-03 16:56:31 UTC 
Please install the debug packages and post a better backtrace, thanks in advance.
Comment 4 Shlomi Fish 2008-09-03 17:32:48 UTC 
Here is the backtrace with the kdebase4-debug and kdelibs3-debug packages installed:

Comment 5 Aaron J. Seigo 2008-09-03 17:58:06 UTC 
you re-openned a bug report that isn't even the same bug that you are reporting. =/ please leave the bug triaging to us; you can leave comments on bugs that are closed and we still get notified of it. better yet, if the backtrace you get doesn't actually match the one in the bug you are looking at, open a new bug.
