Comment 10 for bug 1284052

I don't think that this is a Dolphin issue. I see nothing related to Dolphin in the backtrace. Moreover, the crashes only started with KDE SC 4.10, and there were, to my knowledge, no Places-related changes between 4.9 and 4.10 in Dophin.

However, I do see a change in kdelibs prior to 4.10 which changes the way KBookmarkManager deals with toolbars:

It appears that this commit might be related to the cause of these crashes. I'll CC Stefan Brüns, who committed that change.
