So, let's fix it :)
The term "trivial" triggered me into trying it myself.
The attached patch adds -lGL to LIBS in overlay_gl/overlay_gl.pro
which seems to determine the libmumble build.
The result:
- No more "undefined symbol" errors when starting mumble:

Ok, so the problem is not starting mumble itself, as reported by dkg, but
mumble-overlay / preloading libmumble ...

Ok.

Yeah, seems so :/
Cheers,
gregor, hoping that his patch attempt might be useful
