Bug 207305

Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.30-gentoo-r4-ines i686

What I was doing when the application crashed:
1. choose application launcher settings
2. checked "show appliactions by name" on
3. OK
4. crash
5. setting not saved

Second attempt to turn it on was successful.

 -- Backtrace:
