Any reason why you move these at the very end?

A const gchar* function returning a copy a copy of a string? That looks wrong, but it was like that before already :) But then this is 0.10 code, which was broken exactly because of things like this. So decide for yourself if you want to leak here or potentially crash

I think these locks are actually unnecessary, as that function will only be called right after creating the instance and then never again. But they don't hurt
