Version:           Version 1.3 KDE 4.1.87 (KDE 4.2 >= 20090101) (using Devel)
Compiler:          gcc (SUSE Linux) 4.3.2 [gcc-4_3-branch revision 141291]

Installed from:    Compiled sources

I exited kontact and it crashed. After the crash, all that was left of the mail receiving accounts was parts of the first POP account information, all other accounts were deleted and I had to enter them again, using kwallet for the account passwords. I cannot reproduce this at the moment.

Here's the backtrace:
