Hi Dan,
I tried to run nm-connect-editor(of 0.8.2-beta1), it aborted with "WARNING **: Icon nm-device-wwan missing". (gtk+ 2.18.3)
I copy and rename an arbitrary icon in /usr/share/icons/hicolor/48x48/apps to "nm-device-wwan.png", the UI initializes normally.
Does the source misses this icon for all sizes except 22x22?
According to the
Icon Theme Specification, gtk should load nm-device-wwan.png of size 22x22 automatically. I removed the manually copied icon in 48x48, nm-connection-editor also pops up its window normally, curious, maybe the side effect of the cache ?
