Comment 1 Lamarque V. Souza 2012-10-21 00:00:44 UTC 
Can you check if this problem happen with Plasma NM 0.9.0.3 or even better with Plasma NM 0.9.0.5? There is a bug fixed in 0.9.0.3 that I think could case this crash. Just to be sure I would like you to test the latest Plasma NM version (0.9.0.5) to confirm my suspicions.
Comment 2 uc 2012-12-17 06:05:28 UTC 
Sorry for the delay (death in family).

The version of Network Manager in openSuse 12.2 is 0.9.4.0, from the repository.  I'm not clear on your question:  should I try to install an earlier version (0.9.0.5)?  At this point I'd have to search for that version.
Comment 3 Lamarque V. Souza 2012-12-17 10:56:45 UTC 
Plasma NM is *not* the same thing as NetworkManager. Plasma NM is the widget to control NetworkManager, which is a daemon that run as root (Plasma NM run as normal user). You can check the Plasma NM version by clicking on "Manage Connections"  then in "Other".
Comment 4 uc 2012-12-20 03:35:59 UTC 
widget version is "0.9.0.2 (nm09 20120507)"
Comment 5 Lamarque V. Souza 2012-12-20 08:32:29 UTC 
That version is more than six months old, there have been a lot of fixes since then. You have better upgrading to a newer version, preferably 0.9.0.6, which contains a fix that I think also fixes this problem (commit 64988f79dc199bbd4e96db0ea34f8c5bb6450747).
Comment 6 uc 2012-12-21 02:29:36 UTC 
Thanks for the information.  I downloaded the .9.0.6 version, but found errors in the configure process.  The openSuse repositories seem to lack some of the needed files.  Don't want to take your time on this, but for my benefit, and for others who will find this thread, can you post a link or recommend a source of installation instructions (beyond your blog).  Thanks for your help.
