I added advertisement support to my application today:
https://git.fedorahosted.org/cgit/jelling/linux.git/commit/?id=e04016c8
b7f0d406b39573863cf7d5e15dac53ed

When registering the advertisement with bluez, bluetoothd crashes:

As this was my first attempt at implementing advertisement support, I
may be doing something wrong. If I am, your tips are appreciated!
However, in any case, bluez shouldn't crash.
