Comment 2 for bug 390011

I'm having the same problem (Kubuntu lucid). gupnp-universal-cp was working fine in karmic.
As Mike Pontillo said, I had to install "gtk2-engines", but if "gnome-control-center" is not installed, the app throws the error. "gnome-control-center" (and its long list of dependencies) was installed when Mike and I were testing. I think there are missing dependencies, but I don't really know what the problem is. Other gnome app's are working fine.

These are the dependencies for "gnome-control-center":

I purged "gnome-control-center" and then installed only the lib* ones, but this did not help.
