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:

I was viewing a local folder, successfully sent out an email, and wanted to change to an IMAP folder (INBOX). I pressed j, followed by i for inbox. kmail crashed either after pressing i or after pressing enter afterwards (I do not recall precisely).

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