Comment 1 Jan Grulich 2013-09-26 11:06:43 UTC 
It crashes in the old networkmanagement applet, not in plasma-nm (the new one). Probably there is still running the old kded modul. The script won't be necessary for the upcoming plasma-nm version, because we renamed it so upgrade will be much easier.
Comment 2 Gérard Talbot (no longer involved) 2013-11-13 23:04:39 UTC 
Johnathan, Jan,

Why is this bug WONTFIX? (just asking)
Is bug 327543 a DUPLICATE of this bug?

Just asking.

Comment 3 Jonathan Riddell 2013-11-14 10:11:31 UTC 
Gerard it won't be fixed because it was caused by the applet getting a new internal name compared to the old applet. it's now been renamed to match the old applet so it's no longer a problem.
