KDE Platform Version: 4.8.3 (4.8.3)

-- Information about the crash:
I created a folder under local-folders/Inbox named CLAM.
I configured the CLAM add-in to move questionable messages to that folder.
I moved the CLAM fodler udner local-folders so it was on the same level as Inbox.
I right-clicked on local-folders, selected "New Folder", typed the name "Spam" and clicked Ok.
The failure immediately followed my trying to create a folder.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
