I have the (possibly) same crash using 4.1.0 installed as described on kubuntu.org. I am running a 64 bit system

Here is my crash report (I installed additional dbg packages to help):

Comment 3 Brad Neuman 2008-07-30 03:10:31 UTC
oops, sorry guys I think this is a different bug. I misread the initial post, mine crashes like this as soon as I log in, but kde 4.0 worked fine
Comment 4 Dominik Tritscher 2008-08-04 22:36:26 UTC
@Thomas and G. Christ: Does this crash still occurs with KDE4.1? If so, please try to create a complete backtrace. See http://techbase.kde.org/Contribute/Bugsquad/How_to_create_useful_crash_reports for details.
Comment 5 G360 2008-08-05 21:48:52 UTC
It only crashed twice with 4.1 RC1, but now with 4.1 final it didn't crashed any more. Maybe it is already fixed.
Comment 6 Aaron J. Seigo 2008-08-05 22:36:46 UTC
*** Bug has been marked as fixed ***.
Comment 7 Gabriel Hurley 2008-08-17 18:59:00 UTC
I am still experiencing crashes with the 4.1 update. Here is my backtrace:
