David Bevan has just contributed a major revision to the FreeType stroker; I assume that the issues mentioned here in this bug report are fixed also (I have no direct possibility to check it).

If there are still problems please reopen the bug.

No need to thank me, I'm not the developer.

I simply relayed the message.

"This is a known problem with FreeType's stroker, which is used for creating the bordered glyphs. It probably won't be easy to fix, but I'm working on it.

The FreeType stroker is very sensitive to broken/defective fonts (e.g. fonts that do not follow the TrueType specification) and has a few design shortcomings (breaks when stroking leads to self-intersection)."

Attached is an example of this bug in action. Pay close attention to the border gaps on the glyphs.
