Bug 327755

Application: kontact (4.11.3)
KDE Platform Version: 4.11.3
Qt Version: 4.8.5
Operating System: Linux 3.11.8-200.fc19.x86_64 x86_64
Distribution: "Fedora release 19 (Schrödinger’s Cat)"

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

Nothing special. There was Kontact, Konsole and Chrome running on the computer when Plasma crashed. Kontact displays remote IMAP and CalDAV resources.

KDE is installed from standard Fedora RPM packages.

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