Reproducible: Didn't try
Comment 1 Beat Wolf 2010-09-26 09:28:08 UTC 
what kde version are you using?
Comment 2 Clemens Eisserer 2010-09-26 09:48:07 UTC 
Sorry, I forgot to provide the information. Its 4.5.1, as you can see from the stacktrace: "kdebase-workspace-4.5.1"
Comment 3 Aaron J. Seigo 2010-09-26 21:06:55 UTC 
SVN commit 1180012 by aseigo:

* move some slots to the private class
* delay the signalling from the group that items have been removed; this allows the items to fully delete, preventing possible usage of the item object when it is only half-destructed (and therefore a AbstractGroupableItem with pure virtuals)

a little too invasive to backport without more testing
