Bug 326732

Application: kmymoney (4.6.3)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic i686
Distribution: Ubuntu 13.10

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

I attempted to save my work and the application crashed.  During the crash my data file became an empty file.  I had to copy a backed up version to the normally used file name.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KMyMoney (kmymoney), signal: Segmentation fault
