Title:
nm-applet crashed with SIGSEGV in add_menu_item()
Status in Network Manager Applet:
Confirmed
Status in network-manager-applet package in Ubuntu:
Fix Released
Status in network-manager-applet source package in Vivid:
Fix Released
Bug description:
[Impact]
If for any reason ModemManager is unavailable or unable to understand the
modem device that pops up as broadband (also, in the case of Desktop-Next),
NM-applet may crash due to expecting that there is always a devinfo object from
the ModemManager data.
[Test case]
Install, use desktop, with ModemManager disabled.
[Regression potential]
Minimal, this is a patch from upstream which covers a known issue with NM in
case ModemManager is unavailable to answer requests; what may happen as a
result of devinfo being unavailable but NM continuing without crashing is that
icons and pretty device names or signal level might be unavailable.
