Description Freek de Kruijf 2012-08-29 12:00:25 UTC

-- Information about the crash:
- What I was doing when the application crashed:

I tried to enable the selection box "IPv6 required for this connection" in tab IPv6 of one of my wireless connections. It turned out that after activating the box and later returning the box was not set anymore. I enabled that box again and after clicking OK, this crash occured.

Comment 1 Lamarque V. Souza 2012-08-29 13:24:13 UTC 
Which Plasma NM version do you use? You can see the version by clicking on "Manage Connections" then "Other". I fixed a problem with that button in Plasma NM 0.9.0.3, so you need at least that version to use it.
Comment 2 Freek de Kruijf 2012-08-29 14:29:44 UTC 
I use 0.9.0.2. A higher version is not available in openSUSE 12.2RC2
Comment 3 Lamarque V. Souza 2012-08-29 16:00:41 UTC 
The current Plasma NM version is 0.9.0.4. 0.9.0.2 was released more than three and a half months ago, OpenSuse should really provide more up to date fixes for their users.
Comment 4 Freek de Kruijf 2012-08-31 14:35:51 UTC 
I found 0.9.0.4 in KDE 4.9 Playground Repository for openSUSE 12.1 and 12.2
