  i do not have the full overview to hand, and the codebase is rather large, 
but i know that there is currently in use at least the following:

 * GPLv2 (Creator)
 * GPLv3 (GluonCore)
 * No license at all (some of the files lack license information entirely)

  As i understand it, specifically GPLv3 is a big problem since it's 
incompatible with KDE's library policy.

  For this bit to make sense, i should probably need to explain what i meant: 
Games created using Gluon Creator are not binaries, but rather a collection of 
assets (some of which are scripts defining game logic). What this means is 
that they are more a kind of document - so for licensing purposes you're 
looking at something much closer to an odf file (which is similarly an archive 
with some assets in it, making up a document) rather than a program.
  You are of course correct that the license of the Gluon libraries /will/ 
impact on games like Blok, which do not use Gluon Creator's method of game 
creation, and that's really why this discussion needs to happen :)
