Bug Description

Binary package hint: python2.6

I was interacting with kwallet and kdenetworkmanager when this happened. I don't think either of those use Python, so I'm not sure what's to blame.

python wasn't to blame for this. It was a pain to figure out, but it was something with the KMenu that is issued when you right-click the icon. Definitely a KDE Airplane Mode issue.

Marking this fix committed as I think some of the recent code fixes I did took care of this. Time will only tell.

Google results were pointing the blame at Qt4 X11, so if this comes back we will have to really look into it, but I am hoping that my code fixes took care of this as there were quite a few initial logic issues which seem to be fixed at this time.
