apparmor profile /usr/lib/telepathy/mission-control-5 causes gdm crash

[Karl-Philipp Richter]

Currently the crash is only reproducible with `spotify-client` 0.9.11.27.g2b1a638c after opening the starred playlist, but according to the error message it should be possible to reproduce it with another program (which I'm willing to do if a developer names one). After the crash the output of tty7 is visible for some seconds until `gdm` restarts. The output in `dmesg` is
