Comment 1 Aaron J. Seigo 2008-06-24 23:56:58 UTC
this backtrace isn't very useful. please provide a better backtrace using the information on this page:

http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

thanks...
Comment 2 Sebastian Sauer 2008-06-25 00:32:41 UTC
looks like a duplicate of bug #164653 which was fixed with r823000 (>= Sunday 22 June).
Comment 3 FiNeX 2008-06-25 11:22:07 UTC
@Arnout: you should update your kde version to a more recent one and re-test it.
Comment 4 Arnout Boelens 2008-06-25 17:56:20 UTC
@Aaron: It turned out I missed one Debian dbg package.. I just read on your blog how you wished development packages where with debugging symbols by default. Now I know why :-). When the crash occures again (I does not happen on every logout) I will give the new backtrace.

@FiNeX: I will try when there are new Debian packages. This might take a while though, because the are focusing on getting KDE 3.5.9 in shape for the new release..

Comment 6 Sebastian Sauer 2008-06-26 23:28:00 UTC
I (and someone else) can reproduce the backtrace from comment #5 with Cooker on;

1) remove the dolphin-icon from the panel
2) kquitapp plasma
3) plasma
4) crash

Quit funny since plasma starts then up anyway and the dolphin-icon is still in the panel. So, seems the change wasn't saved on the one side but somehow is able to lead to a crash on startup on the other side what is more then illogical imho.

Comment 8 Sebastian Sauer 2008-07-05 23:57:11 UTC
interesting duplicate-roundtrip of this crasher and following it

Ok, once more; let's mark this bug as duplicate of bug #163607 (cause same backtrace and cause at the other report we already got closer to a solution ;)
