@erlehmann can you please take a look at this? I just tried a fix via f42313c but it does not seem to have been enough.

[Daniel-Mietchen]

Does not work.

[erlehmann]

Please wait with this until the wmde-review branch is merged. It contains a refactoring of some of logic regarding licensing heuristics. Daniel Kinzler said he would put 2 hours into that this week. Meanwhile, I can add this as a test case to the wmde-review branch and see if it works.

[erlehmann]

Works on the wmde-review branch, see commit aee79b3.

[Daniel-Mietchen]

OK, thanks.
