Description vono22 2010-09-26 12:57:19 UTC
Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic x86_64
Distribution: Ubuntu maverick (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
I have setup another network connection on the same device (eth0) than the default (not visible), to change the default DNS.
It didn't change anything (dns takes too long to response), so I figure I done an error.
My new connection was active, and i delete it. -> Crash

- Step to reproduce (I test this scenario twice):

1) In the plasma network app (like the windows systray ?) left click to show the popup
2) Click the button "Manage connection"
3) Add a new Wired connection (may work with other type...)
4) Click ok to save this connection
5) Close the "Configure - KDE Control Module" by clicking the Ok button
6) In the network systray app, select your new connection
7) When this connection is active, reopen the network manager with the systray network app.
8) Delete your new connection
9) -> Crash.


OS: Kubuntu 10.10 x86_64 KDE 4.5.1
