Reproducible: Always

Steps to Reproduce:
1. Open kmail, either on console or from menu
2. Application crashes after a brief display of the UI
3.
Actual Results:  
Instant crash

Expected Results:  
Display mail accounts/folders

Incidentally, I also use Kmail (KDE3) on the same mail folders, which is a lot
more stable, but I suspect that the two kmails clash on how they mark the
messages (deleted, read, ..)
