Description Paul Konecny 2013-08-26 12:34:55 UTC 
Application: kded4 (4.11.00)
KDE Platform Version: 4.11.00
Qt Version: 4.8.4
Operating System: Linux 3.11.0-3-generic x86_64
Distribution: Ubuntu Saucy Salamander (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
Logging in to KDE 4.11 (Kubuntu 13.10 saucy developmental release), I noticed that nm-applet won't connect to wifi after I entered my KWallet credentials. (it just shows the signalbars with the key and is awaiting authorization). 

- Unusual behavior I noticed:
Switching wifi off and on again causes nm-applet to crash. After it reloads, it connects just fine. 
Happens almost everytime I log in. 

On a sidenote:
My original intention was to use wifi without Kwallet (unencrypted) but even when i changed the setting nm-applet would still try to access KWallet even though I saved my wifi-key in the unencrypted file. I doesn't seem to apply my change.

I hope we can work this issue out. Other than that 4.11 is amazing! 
Regards, Paul

The crash can be reproduced every time.

Comment 1 Paul Konecny 2013-09-02 11:03:31 UTC 
UPDATE:
I think I've found the root of the problem. Today, after I logged in two Icons for networking showed up. 
My guess is that one is the "old" version and one is the new QML version (from what I've read over at planetkde.org).
Removing the old Qt one solved the crash issue but now rekonq isn't able to connect to the internet anymore. (Pings and Firefox seem to work fine).
So this may just be a packaging issue on the kubuntu side.

Old Qt network management

The "old" Network plasmoid doesn't seem to get access to the network list anymore.

New QML network management

The new one seems to work fine.
Comment 4 Lamarque V. Souza 2013-09-02 11:45:59 UTC 
Which Plasma NM versions do you use? You can see the version string in "Manage Connections" -> "Other" for the old applet and in "Edit Connections" -> "About" -> "About Connection Editor" for the new QML applet.

Thanks for the quick reply Lamarque!
