Blueman-applet uses 100% cpu

[Ville Ranki]

I'm doing some bluetooth development so I connect and disconnect devices often. I managed to get blueman-applet to a state where it uses 100% cpu. Any of test programs are not running so this is a fault in blueman-applet.

May be related to #667701

Here's a stack trace of blueman-applet eating up 100% cpu:
