Description gary lucas 2011-06-25 03:30:57 UTC
Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.3 (4.6.3)
Qt Version: 4.7.2
Operating System: Linux 2.6.38.8-32.fc15.x86_64 x86_64
Distribution: "Fedora release 15 (Lovelock)"

-- Information about the crash:
- What I was doing when the application crashed:
Immediatly after running yum update, KDE crashes on login.  This is 100% reproducable and appears to happen just after network manager loads.
Once logged in (With no KDE) I can alt+f2 and open console and manually start service network.

When I try to get status of NetworkManager:
sudo service NetworkManager status
NetworkManager.service - Network Manager
          Loaded: loaded (/lib/systemd/system/NetworkManager.service)
          Active: failed since Fri, 24 Jun 2011 20:24:33 -0700; 3min 28s ago
         Process: 1733 ExecStart=/usr/sbin/NetworkManager --no-daemon (code=exited, status=1/FAILURE)
          CGroup: name=systemd:/system/NetworkManager.service

If I try to start NetworkManager it briefly starts up and then dies.  I need to restart network to get connectivity back.

NetworkManager info:
sudo yum info NetworkManager
Loaded plugins: auto-update-debuginfo, langpacks, presto, refresh-packagekit

- Unusual behavior I noticed:
KDE crashes, NetworkManager crashes.

The crash can be reproduced every time.

I'm fairly certain now that the problem is in the KDE Plasma plugin.
Comment 2 gary lucas 2011-06-25 05:07:17 UTC
Sorry, plasma applet
Comment 3 Lamarque V. Souza 2011-06-25 15:03:51 UTC
This problem was fixed two months ago, please upgrade to a newer Plasma NM snapshot.
