Bug 199021

Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.95 (KDE 4.2.95 (KDE 4.3 RC1))
Qt Version: 4.5.0
Operating System: Linux 2.6.28-13-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I get a plasma crash when adding or removing a wired connection in the network management widget. To reproduce:

- open "Manage Connections.." from the context menu
- in the "Wired" page select "Add..."
- fill in some data. The actual content doesn't seem to matter. I only inserted the MAC address and left the rest as is.
- close by clicking "Ok"
- then I'm prompted to enter the password to open the wallet. I do so.
- the new connection is added to the list (i.e. it appears there)
- and right after that: crash!

I know the backtrace is a bit suboptimal... but there seems to be no package with debug information for plasma_applet_networkmanagement.so in the 4.3rc1 Kubuntu packages...
