Error on select rectangle

[kontur]

When I activate the plugin the glyph gets rendered black (fantastic!) but I get errors in the Macro panel that prevent editing.

Show Black Fill error (getHandlesInfo): global name 'GSOFFCURVE' is not defined
Show Black Fill error (foreground): 'NoneType' object is not iterable

Does it happen in certain glyphs? If so, could you send me the Glyphs file with only that glyph? (I mean you can leave everything in if you don't mind)

Happens in any file or glyph, also a new file, when drawing to any glyph. I can draw a shape, and it appears filled, but the error pops up the Macro panel after every interaction with the drawing area. Glyphs is Version 2.5.2 (1153).
