ah, this is something that should have been fixed some days ago (193042 and its dupes) ... but before r986105 sooo, there is still some problem in that area, sigh :(

@Marco: Is this related to the latest Aaron blog post?

FiNeX: yes, exactly :)

SVN commit 986504 by aseigo:

adding items can result in a change in strategy, prepare for it.

(with my changes from the other day, these bugs are at least becoming easy to figure out; in this case groupManager == 0 means it was changed on us, making the fix evident)

This bug seems still present in latest Karmic packages (Jaunty probably too).
I had this problem once with Jaunty, about one week ago, and today same crash again on Karmic, with latest updates. This time I was closing firefox, in Jaunty I believe it was some other program, but I don't think it's relevant.

Below is the bug report from the KDE Crash Handler

I think that this problem is not fixed yet. Or is it?
How can I fix it?

@tijnema:   

All the recent reports (the ones with usable backtraces, that is) appear to still make reference to a call to manualSortingRequest(...) at line 167, but after Aaron's fix in r986504, this call was bumped down to a later line.

So it looks like the recent reports simply don't have the fix applied, and I don't see any evidence that the bug is not fixed.

I'm sorry. I've checked the source package of kubuntu's kdebase-workspace-4.2.95 and it doesn't have the fix applied.

Well, it is fixed with the Fedora 4.2.95 updates from kde-redhat repo. No plasma crash since the patched updates.

*** Bug 199538 has been marked as a duplicate of this bug. ***

Works for me on F11 since I upgraded kdebase-workspace to 4.2.95-7

I agree.  kubuntu Jaunty with updates applied, plasma bombs on me several times a day.

Well, according to "it's fixed with kdebase-workspace-4.2.95-7 update in Fedora10/11" looks like it's now a Kubuntu Packaging/Patch issue. You might consider to file a bug on their Bugtracker. It is fixed.

Woohoo! This is the most frequently reported bug:

https://bugs.kde.org/duplicates.cgi

Technically this isn't Kubuntu's fault, it seems that the tarballs for KDE 4.3 RC1 didn't include the fix.

So it's a good thing RC2 is out :-) still waiting to update my kde packages in kubuntu because i wanted to have a fixed version..

Well, of course not, crashing started with RC1. Well since Dan filed the Bug on their Bugtracker, they hopefully will fix it fast ;)

RC2 has hit Kubuntu and it appears to be fixed there.

I'm still getting crashes with RC2 in Kubuntu. see bug 199894

RC2 here, and the only way to start KDE after my crash is to delete my ~/.kde.
That's not cool.
