@FabianLars I also tested on Windows and got the same error, so my guess is it's a platform independent bug.

[FabianLars]

Do you still have the full error from the Windows test? I doubt it's exactly the same since we don't use GDK on Windows so it'd be interesting to see where it panics.

[bicarlsen]

Oops, it appears it is working on Windows now. I must have messed something up when testing the first time. Sorry about that.
