Application: kmail (4.8.3)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-25-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Just logged in.  KDE had not restarted Network Manager ( fairly consistent issue ).  Kmail started, asked about working offline, but had not accessed kwallet.  Before I answered the offline dialog, kmail crashed.

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