description |
The crash is reported while using the bluetooth settings. The way to trigger it:
1. While bluetooth is enabled - open bluetooth settings, everything works.
2. Turn off bluetooth using laptop wireless killswitch (I'm on Thinkpad W500)
3. Turn on the killswitch
4. Bluetooth settings don't reflect the fact that bluetooth is enabled (cannot enable or disable in settings) now and a crash is reported.
5. Restarting bluetooth service fixes the settings behaviour

[Impact]
Removing a pairing or toggling the killswitch when a PAN/DUN capable device is paired to the bluetooth system triggers a crash because bluetooth keeps a reference to the connections in NMRemoteSettings objects that have already been freed, which causes update signals to still be called on these objects.
[Development Fix]
Fixed upstream, as http://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=494f0a2e2047ca42adc73ecd6080068ce1fc9687. See https://bugzilla.gnome.org/show_bug.cgi?id=674484 (upstream bug). This change only affects NetworkManager's code, doesn't require rebuild of any dependant package.
[Stable Fix]
See above "Development fix".
[Test Case]
1) Connect a phone capable of DUN or PAN to bluetooth control panel.
2) Remove the connection with the "-" button in bluetooth control panel.
[Regression Potential]
Low, current handling was clearly wrong. This affects users of NMRemoteSettings only, so limited to a distinct number of packages: network-manager (for the nmcli binary), network-manager-gnome (nm-applet), gnome-shell (for the network indicator).
