Hmm, so from that reply:

I claim it's not obvious that the use of cervisia is okay then.  On one
hand, quanta only uses the KPart functions and does not recast as an
explicit cervisia part, so quanta is using the generic kpart interface.
On the other hand, quanta is in fact requiring this specific non-GPL
part, since the plugin that ships with quanta is explicitly configured
to open libcervisiapart.so.
