Bug 329504

Application: kontact (4.11.4)
KDE Platform Version: 4.11.4
Qt Version: 4.8.5
Operating System: Linux 3.12.6-1.g080d0df-desktop x86_64
Distribution: "openSUSE 12.3 (x86_64)"

-- Information about the crash:
I'm in the process of migrating from one IMAP server to another. Both should contain very similar data. I changed the IMAP server in the configuration, which caused Kontact to crash. I'm not absolutely sure, but I think I had one folder of the affected account selected.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
