Here's a backtrace of unity-system-compositor! :)

I have qtcore, qtdeclarative and libunity debug packages installed.

Moreover, I installed the following packages as suggested by kgunn:
libmirserver33-dbgsym libmirclient9-dbgsym libmircommon5-dbgsym libmirplatform9-dbgsym libmirprotobuf1-dbgsym mir-client-platform-android3-dbgsym

NOTE: when I first tried to take the bt, the compositor had PID 1574.

I attached gdb to it, and while it was loading the dbgsyms I think the compositor died.
I checked top, compositor now had PID 1575.

UI still frozen, power button still not responding.

I attached gdb to it again, and got the bt that you can find attached.
