Bug 324077

Application: systemsettings (4.11.00)
KDE Platform Version: 4.11.00
Qt Version: 4.8.4
Operating System: Linux 3.8.0-29-generic i686
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed: I had gone into Workspace appearance to review a KDE setting.  When I attempted to return to the main system settings page by clicking the back arrow, the application crashed.  There appear to be several bugs of similar nature but with earlier versions of KDE SC, so I didn't mark as duplicate.  

For what it is worth, I changed my icons a couple of days ago after having not changed them for a year.  This change probably has nothing to do with it but I wanted to add it just in case.  Thanks!
