- What I was doing when the application crashed:

Trying to reestablish Wi_Fi connection after it dropped.  Entering passphrase and ENTER triggered crash.   Has happened twice in two days on new install of openSuse 13.1 on Dell poweredge 2970 (AMD CPUs).  Wi-Fi on USB-attached dongle, ASUS wireless N adapter.  It had been connecting regularly at 65 Mbit/s.

The crash can be reproduced sometimes.

Comment 1 Lamarque V. Souza 2013-12-29 14:43:38 UTC 
Which Plasma NM version do you use?
Comment 2 uc 2013-12-29 22:01:07 UTC 
YaST2 shows as installed:
NetworkManager-kde4-libs           NetworkManager client for KDE 4    0.9.0.7-1.4.1
plasmoid-networkmanagement    NetworkManager client for KDE 4    0.9.0.7-1.4.1
Comment 3 Lamarque V. Souza 2014-01-18 20:36:10 UTC 
According to the crashlog you are using Plasma NM 0.9.0.10. If those two libraries above are really version 0.9.0.7 then you have a binary incompatible version of those libraries. You should make sure every package related to Plasma NM use the same version (0.9.0.10 in this case).
