Version:           SVN 4.2 branch 2/2/09 (using KDE 4.2.0)
Compiler:          gcc 4.3.2

Installed from:    Compiled From Sources

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. The crash trace is the first one shown below.

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