Description K900 2011-10-11 06:54:22 UTC 
Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.4 x86_64
Distribution: "AgiliaLinux release 8.0.0 (Sammy)"

-- Information about the crash:
- What I was doing when the application crashed:
Added the Network Management plasmoid to a panel. Happens both with a panel and a desktop.
- Custom settings of the application:
Latest compile (as of just now) from nm09 branch, NetworkManager 0.9.1.90, KDE 4.7.2 on AgiliaLinux (Slack-based). nm08 branch works fine, 0.8.80 release also crashes.

The crash can be reproduced every time.

-- Backtrace:

Comment 1 K900 2011-10-11 06:57:02 UTC 
Can be reproduced both on my setup and on a clean system (in VirtualBox or with mv ~/.kde ~/.kde_test)
Comment 2 K900 2011-10-11 09:31:13 UTC 
Tested again with 0.8.80. Strangely it works now. The latest git still crashes.
Comment 3 Lamarque V. Souza 2011-10-11 17:18:32 UTC 
I am not able to reproduce this problem. 0.8.80 and latest git are almost the same, this look like a intermitent problem.
Comment 4 K900 2011-10-11 17:25:47 UTC 
Hmmm... I'll try to get somemore info with gdb and see why it crashes.
Comment 5 K900 2011-10-12 06:55:42 UTC 
Strange, doesn't segfault anymore. OK, setting as worksforme.
