when _getGlyphNamesFromCmap gets called by the cmap parser itself, the partially loaded subtable is removed and then restored later. However, when a TTFont instance is imported from XML rather than from binary file, its 'reader' attribute is None, and so the line: tempcmap = self['cmap'].getcmap(3, 1) will make TTFont.__getitem__ raise KeyError. It's better to fail nicely, and return a dummy glyphOrder based on maxp numGlyphs.

History
The fontTools project was started by Just van Rossum in 1999, and was maintained as an open source project at http://sourceforge.net/projects/fonttools/. In 2008, Paul Wise (pabs3) began helping Just with stability maintenance. In 2013 Behdad Esfahbod began a friendly fork, thoroughly reviewing the codebase and making changes at https://github.com/behdad/fonttools to add new features and support for new font formats.
