Application that crashed: systemsettings
Version of the application: 1.0
KDE Version: 4.2.96 (KDE 4.2.96 (KDE 4.3 RC2))
Qt Version: 4.5.0
Operating System: Linux 2.6.28-13-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
After adding Microsofts Consolas font, the systemsettings crashed.  I first installed the regular version of the font, that worked ok. Then I installed italic/bold version, Consolas entry in tree view was already open, and it crashed.
