Application: kcmshell4 (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-13-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:
When I wake up my laptop from suspend to RAM and want to enable my external monitor the "Display Settings" dialogue crashes after I hit "Apply". Sometimes this does not happen, but the more often I set the laptop to sleep and wake it up, the more likely it is. Workaround is to logoff and logon again (KDE drestart).
I marked this bug as not related to the general problems with the Display Settings (Bug 327928) since it is not a general problem.

- Custom settings of the application:
Related to supend to RAM.

The crash can be reproduced sometimes.
