Application: kmail (4.7.2)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

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

kmail startet with a GnuPG encrypted mail selected and the passphrase entry dialogue appeared. I left that window open and clicked "fetch new mail" and kwallet asked for the password to unlock the wallet. I entered it, hit return and then kmail crashed immediately.

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