Application: korganizer (4.8.5)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-38-generic x86_64
Distribution: Ubuntu 12.04.2 LTS

-- Information about the crash:
I used to get this every time I closed KOrganizer, but have not had it happen for some time until today.

- What I was doing when the application crashed:
I was closing down my applications one by one so I could apply updates and then reboot.  I had not changed anything in KOrganizer for many hours.

- Unusual behaviour I noticed:
During this session of use I had been playing 0AD which appears to have a memory leak.  It had consumed the rest of my 8 GB of RAM and 2B of the cache.  I close that down yesterday and that did not free up more than 2GB of RAM.  By this morning memory use was back down to 1Gb of RAM - is there some clever memory clean-up program working here that has been over-zealous?  That's all just speculation on my part, of course.

-- Backtrace:
Application: KOrganizer (korganizer), signal: Segmentation fault
