Application: kplato (0.10.3)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-17-generic x86_64
Distribution: Ubuntu 11.10

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

I was running KPlato. I can do all kinds of modifications in KPlato without problems. Then I close the application and consistently get the attached abort. I do not see any weirdness either in KPlato or in the system in general. This has happened several times in the past, no corruption of KPlato files occurs, but as it repeats itself, and doesnt seem to be a duplicate, I felt compelled to send in the bug report. I will be happy to provide any extra information required.

I also checked some other bugreports, specifically one on DBUS and one on KRITA, both dont seem to reflect this problem (i look at this as a user, not a programmer).

The output of uname -a is:
gbonnema@mahatma:~$ uname -a
Linux mahatma 3.0.0-17-generic #30-Ubuntu SMP Thu Mar 8 20:45:39 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

This distribution was obtained through regular distribution channels. To my knowledge I installed a version of KUbuntu.

The crash can be reproduced every time.
