[Apport retracing service (apport)]

This crash has the same stack trace characteristics as bug #1189309. However, the latter was already fixed in an earlier package version than the one in this report. This might be a regression or because the problem is in a dependent package.

[Launchpad Janitor (janitor)]

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

[Robert Ancell (robert-ancell)]

The bug was libappindicator calling unfallback() when the applet is being unrefed. This would cause it to access the status_icon which had been unreffed in the previous step.

[Launchpad Janitor (janitor)]

This bug was fixed in the package network-manager-applet - 0.9.8.0-1ubuntu5

---------------
network-manager-applet (0.9.8.0-1ubuntu5) saucy; urgency=low
