Bug 176083

Version:            (using KDE 4.1.3)
OS:                Linux
Installed from:    Ubuntu Packages

When trying to add a program to a file type that has no entries (in my case video/divx) systemsettings suddenly crashes with signal 11 (SIGSEGV)

This is what I get from crash manager:

Applicazione: Impostazioni di sistema (systemsettings), segnale SIGSEGV
