Comment 30 for bug 124336

aot2002: I've just looked at your logs and the last time I see the SIGSEGV is:

Oct 29 08:15:10 localhost kernel: [ 103.908729] nm-applet[6066]: segfault at ffffffffac043cc0

After that I see:

Oct 29 08:21:06 sudo: USER=root ; COMMAND=/usr/bin/killall nm-applet
Oct 29 08:21:45 sudo: USER=root ; COMMAND=/usr/bin/nm-applet
Oct 29 08:21:53 sudo: USER=root ; COMMAND=/usr/bin/nm-applet

which indicates you're running nm-applet as root. This is incorrect. nm-applet should be run as a regular user application without using sudo:

$ nm-applet

If the errors in your earlier report were reported after starting nm-applet as root, the dbus-related errors would be expected. Please kill any running instance of nm-applet and start it without sudo and see how it goes.
