I think the wrong developer has been added - the issue was not caused by
bc66d7edde877877ef7f601926520fc2e3209a43 but by
bc449ca31fbd4a97ef1a06cabbfb2787e2ea6ca1 (first one was a red herring). 
Developer should be Author: Stefan Dösinger <stefan at codeweavers.com> I think.

Been working on identifying what breaks it. This change breaks it.

When not working, Im now getting the following errors as well.
