I guess FT_Get_Glyph fails for Helvetica, but then why does Helvetica
show up in the font selection dialog?

Comment 1 Lars Clausen 2004-06-12 19:17:37 UTC

Interesting.  I'm guessing that something is broek with freetype or that font,
as the crash happens internally in freetype when it's looking at its own
datastructures.

Comment 2 fnatter 2004-06-15 08:21:08 UTC

should I report a bug to freetype?

Comment 3 Hans Breuer 2005-12-27 19:25:10 UTC

[btw: I could easily reproduce with a probably different freetype version]

2005-12-27  Hans Breuer  <hans@breuer.org>

	* app/diapsft2renderer.c(draw_bezier_outline) : only call
	FT_Outline_Decompose() when FT_GLYPH_FORMAT_OUTLINE.
	Prefers no text output over crashing for bug #144212
