2012-04-25 14:51:56 Mathieu Trudel-Lapierre 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 ProblemType: Crash DistroRelease: Ubuntu 12.04 Package: gnome-control-center 1:3.3.91-0ubuntu1 ProcVersionSignature: Ubuntu 3.2.0-18.28-generic 3.2.9 Uname: Linux 3.2.0-18-generic x86_64 ApportVersion: 1.94.1-0ubuntu1 Architecture: amd64 CrashCounter: 1 Date: Wed Mar 7 23:50:03 2012 ExecutablePath: /usr/bin/gnome-control-center ProcCmdline: gnome-control-center bluetooth SegvAnalysis: Segfault happened at: 0x7f0fc6cfc4ac: mov 0x28(%rax),%rdx PC (0x7f0fc6cfc4ac) ok source "0x28(%rax)" (0x00000028) not located in a known VMA region (needed readable region)! destination "%rdx" ok SegvReason: reading NULL VMA Signal: 11 SourcePackage: gnome-control-center StacktraceTop: ??

[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). --------- The crash is reported while using the bluetooth settings.
