KDE 4.13.3 (KXStudio)

When attempting to resize System Settings window, or using scrollbar to get to
bottom, System Settings crashes. Tried resizing by bottom, sides, and corner,
and top resize button. Crashes every time. Tried reinstalling System Settings
through Synaptic and problem persists.

Reproducible: Always

Steps to Reproduce:
1. Resize System Settings window
2. Crash
3. Restart, go back to 1. ;)

Actual Results:  
Crash

Expected Results:  
Ability to access the bottom row of System Settings.

Also, attempting to report this, I went through the steps and installed debug,
created account-- then when finally submitting, it said I wasn't logged in. So
I'm here now.

I saved the report info to a text file, copy/pasted below:

KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.13.0-35-lowlatency x86_64
Distribution: Ubuntu 14.04.1 LTS

-- Information about the crash:
