Good question.
I didn't debug the font to have a detailed log (it usually takes a long time). I just passed the font through my test programs (as I said, I'm already used to this kind of thing). The program that tests the geometric data (lines and splines) integrity failed.
From my previous debugging sections, the most common errors I already got are:
- shapes with just one point;
- shapes with several points, but all are the same;
- shapes with zero area (just 2 points, or many collinear points);
- splines with unexpected end (missing points);
- glyphs with positive polygons that are inside negative polygons (holes).
If it doesn't make sense for you, never mind. I was just trying to say that the font is guilty, not gimp.
