Control: fixed -1 1.0.2-1 I've encountered this issue too when connecting a Nokia C5 via USB to my laptop to share its internet connection, nm-applet crashes every time I unplug and then re-plug the phone. I tried the patch suggested by Morten and I can confirm it solves the issue.
Digging into the upstream changes I've found that this was actually fixed in the version 1.0.2 with this commit: https://git.gnome.org/browse/network-manager-applet/commit/?id=ef2d9f5 This version also fixed another crash in applet-device-broadband.c: https://git.gnome.org/browse/network-manager-applet/commit/?id=d6e73ba Michael if you are busy I'm volunteering for preparing a stable update fixing this issue. Please let me know if this is ok for you. Emmanuel Bourg
