Application: kmail (4.9.4)
KDE Platform Version: 4.9.4
Qt Version: 4.8.3
Operating System: Linux 3.5.0-21-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
Creating a new folder entitled 2012 in LocalFolders/Archive. After confirming the name, Kmail crashed. Restarting Kmail showed the folder actually existed.
Creating further subdirectories after restarting LocalFolders/Archive/2012/Sent, etc. did no longer crash Kmail.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
