Report to https://bugs.kde.org

Reproducible: Didn't try

Steps to Reproduce:
Boot Suse 11.4 live CD and attempt to configure a broadband connection with
parameters for MTN South Africa (not on dropdown list of providers).

Actual Results:  
Executable: kdeinit4 PID: 10058 Signal: Segmentation fault (11)

Expected Results:  
Proceed with configuration for broadband service provider

I think some work needs to be done to improve the 'robustness' of Network
Manager. It frequently fails with broadband connections I have had problems  on
both Ubuntu and Suse Linux installations.
