###!!! ASSERTION: degenerate transform while synthetic bolding: 'm != 0.0', file gfx/thebes/gfxFont.cpp, line 3128

This assertion was added a long time ago, in bug 674909. My guess is I didn't find it until now because I only recently started fuzzing the 'font' property of canvas elements properly.
