-- Information about the crash:
- What I was doing when the application crashed:

when launching Kmail with moderatly sized inbox (between 200-20000 mainly short mails), kmail keeps crashing and complaining that the index is corrupted. The kde folder is on a smb share.

The crash can be reproduced every time.

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