Bug 718622

Created attachment 511104 [details]
Backtrace

Description of problem:

When clicking on the Device Viewer in KInfoCenter, the program crashes or freezes. Removal of NetworkManager seems to fix the problem, but reduces the OS's functionality.

Version-Release number of selected component (if applicable):

KDE 4.6.3 (kdebase-workspace-4.6.3-5.fc15.x86_64)
Network Manager 4.git20110620.fc15

How reproducible:

Reproducibly crashed at first, then became reproducibly unresponsive. I don't know what changed. After removing NetworkManager via yum, kinfocenter works as expected. Reinstalling NetworkManager causes the bug to return.

Steps to Reproduce:
1. K Menu -> System -> KInfoCenter
2. Device Information
3. Device Viewer
  
Actual results:

Crash or unresponsive.

Expected results:

Device list in right pane.
