Bug 279676

Version:           4.7 (using KDE 4.7.0) 
OS:                Linux

When I logged in and when I manually started kded4, it crashed. Here is the backtrace:

Reproducible: Always

Steps to Reproduce:
The file .kde/share/config/servicetype_profilerc contained:

[SolidNetworkManager]
Entry0_Preference=3
Entry0_Service=solidbackends/solid_networkmanager07.desktop
Entry1_Preference=2
Entry1_Service=solidbackends/solid_wicd.desktop
Entry2_Preference=1
Entry2_Service=solidbackends/solid_fakenet.desktop
NumberOfEntries=3


Actual Results:  
kded4 crashes with this setup

Expected Results:  
kded4 shold be able to detect that nm07 isn't available, and use the current version (in this case nm09) instead.

KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.3
Operating System: Linux 3.0.0-7-generic i686
Distribution: Ubuntu oneiric (development branch)


When I removed the text shown below from servicetype_profilerc, and started kded4 from the command line it worked as it should again:

[SolidNetworkManager]
Entry0_Preference=3
Entry0_Service=solidbackends/solid_networkmanager07.desktop
Entry1_Preference=2
Entry1_Service=solidbackends/solid_wicd.desktop
Entry2_Preference=1
Entry2_Service=solidbackends/solid_fakenet.desktop
NumberOfEntries=3

After that I started systemsettings, and went to Information Sources and set networkmanager to have top priority in Network Management Backend. servicetype_profilerc now shows:
[SolidNetworkManager]
Entry0_Preference=3
Entry0_Service=solidbackends/solid_networkmanager09.desktop
Entry1_Preference=2
Entry1_Service=solidbackends/solid_wicd.desktop
Entry2_Preference=1
Entry2_Service=solidbackends/solid_fakenet.desktop
NumberOfEntries=3
