-- Information about the crash:
I have been trying to use kontact-16.12.2. Its been causing trouble since I upgraded to it. It gives an error message about losing contact with the back end. If I shut down kontact and restart it, it immediately segfaults. Prior to segfaulting it had the following in syslog:
