Comment 2

[Jonathan Kew [:jfkthame]]

The failure here occurs because something went wrong reading one of the test fonts:

> 11:51:10     INFO -  [1261] WARNING: Bad font metrics for:
> ufRe3aI+anTJqcdOXIu6Bpbg== (invalid unitsPerEm value): file
> /builds/slave/fx-team-osx64-d-00000000000000/build/gfx/thebes/gfxMacFont.cpp,
> line 221

This looks suspiciously like the warnings mentioned in bug 995970 comment 2; I suspect the same underlying issue is responsible, it just happened to show up on a different testcase this time.
