But that one is supposed to be fixed in RC 2 (at least I could reproduce that bug before the commit mentioned there, but not after it).

Bug 245653 also looks like it could be related.
Comment 3 Frank Reininghaus 2010-08-19 11:43:50 UTC
I think that this is the same issue as bug 247618 which I can now reproduce
(the root cause is a dangling pointer in DolphinView).
