Please write plain text emails; it's far easier to read and answer for
me than reading HTML-formatted emails.  Your email is both plain text
and HTML, but the plain text part is badly formatted.

It's hard to track this without having input.  Can you provide the
font and the used parameters for calling the rasterizer (font size,
offsets, etc.)?  According to the backtrace you've sent, the problem
should be reproducable with a call to FT_Outline_Get_Bitmap.  Maybe
you can write a small test program which just calls this FreeType
function (with proper initialization, of course), and which you feed
with the corresponding input data.

In case the font is proprietary, please send it to me privately, or
use FontForge (or any other font editor) to just extract the
problematic glyph.
