            Bug ID: 324064
           Summary: Nm-applet can't connect to wifi, crashes after
                    disabling/re-enabling wifi with wireless-killswitch
    Classification: Unclassified
           Product: kdelibs
           Version: 4.11.0
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: kded
          Assignee: unassigned-bugs at kde.org
          Reporter: paul at konecny.at

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.
