Bug 285957

Application: kcmshell4 ()
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-13-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
KDE crashed while I attempted to install my Epson M1200 using a PPD. 

Crash can be replicated all the time. 

Installation always worked on previous versions of Kubuntu. Crash only happens with 11.10

The crash can be reproduced every time.

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