Application: kcmshell4 ()
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04.2 LTS

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

Seems like other users are having this error, basically ntp isn't working, I try and fix it, it tells me KControl dies..

Its not the only time something has crashed, I've also noted that the Virtual Terminals seem to be misbehaving, and I was seeing some weird behavior.

I was running Bind9 (unloaded/uninstalled it as it wasn't configured properly), so its possible something isn't getting unloaded/loaded properly.

-- Backtrace:
Application: KDE Control Module (kcmshell4), signal: Segmentation fault
