Thank you very much for the details, this helped to track down the issue. Interestingly it was the second change that triggered the problem. When loading theme tiles from a single image the code relies on the method TIFFRepresentation to create a new bitmap image representation as a side effect. With my change I had accidentally broken this behaviour as now TIFFRepresentationOfImageRepsInArray: on NSBitmapImageRep would always return a (potentially empty) NSData object. I changed this back to the old behaviour and now the theme works again.
