Bug 301693

Application: kmail (4.8.3)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.2
Operating System: Linux 3.4.0-1.fc17.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- 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
Using host libthread_db library "/lib64/libthread_db.so.1".
