-- Information about the crash:
I've logged onto a remote machine via ssh. I've run akonadictl start at first (to get kwallet prompt, as sometimes the kmail request times out and then the wallet becomes unavailable for the whole session ...) Then I've run kmail and it just crashed on start.

The crash can be reproduced sometimes.

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