kmail seems to crash very reproduceably when moving local folders.

I usually easily reproduce it by having /LocalFolder/FolderA and
/LocalFolder/FolderA/FolderB, and try moving FolderB to LocalFolder.

If not during the move, on the next click on the folder it crashes most of the
times.

The backtrace always finishes in the folderType() method:
