Application: kmail (1.13.2)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Tried to set up my first e-mail account for KMail (usually I use Thunderbird).  When the wizard asked for the server type, I selected "Disconnected IMAP" because I don't know what that is and wanted to try out.  Anyway, I think the server is of ordinary "IMAP" type, so maybe this has caused the crash? (When I look at the call stack, this doesn't seem to be plausible...)

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