nm-applet crashes upon activating mobile broadband device

[Rüdiger Kupper]

Selecting "activate mobile broadband" from the nm-applet-indicator reproducibly crashes nm-applet. (Indicator symbol disappears.)
The mobile device is nonetheless activated.
nm-applet can be restartet from the commandline.

Status changed to 'Confirmed' because the bug affects multiple users.

Same here, this seems to be a regression bug - didnt happen to me on 14.10
When i start NM-Applet from the terminal i get the following message at the time of the crash

nm-applet:ERROR:applet-device-broadband.c:636:get_icon: assertion failed: (info)
Aborted

before that i only saw
** (nm-connection-editor:5944): WARNING **: Unsupported connection type 'generic'
** (nm-connection-editor:5944): WARNING **: Unsupported connection type 'generic'
** (nm-connection-editor:5944): WARNING **: Unsupported connection type 'generic'
(nm-applet:5932): nm-applet-WARNING **: Could not find ShellVersion property on org.gnome.Shell after 5 tries
**

Furthermore the applet is still running - even the connection works

This bug also affects me, nm-applet crashes almost completely reliably on resuming from standby and autoconnecting to mobile broadband.
