Bug 226847

Application that crashed: kontact
Version of the application: 4.3.5
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.12-174.2.3.fc12.x86_64 x86_64

What I was doing when the application crashed:
Seems to be duplicate to bug #184615 (I did the same actions in my case).

[Copied from bug #184615]: I had a saved search on an IMAP folder. I clicked Find Messages in the search folder's context menu, and entered a new search (with the aim of redefining the search for the folder), at which point kmail crashed. 

Thereafter, any time the search folder was selected in the folder list, kmail crashed again. Evidently the search folder configuration got corrupted in such a way that kmail could no longer handle it gracefully.

This bug is reproduceable every time.
