Hi,

just testing d.text.freetype on GRASS 6.3 (including just-now fix from
Glynn for main.c) I'm still getting a crash (SIGFPE) if the text=""
contains a space. The debugger traces it to this call in main.c (line
1040).

        if(FT_Render_Glyph(face->glyph, ft_render_mode_mono))
	{

i.e. it breaks within FT_Render_Glyph() if ch=32; it doesn't make it as
far as Glynn's new code (the next line).

in the terminal:
Floating point exception
Monitor <x0>: Premature EOF

Similar problems with GRASS 6.0.2 and 6.1.0 (!). I'm a little surprised
to find this in 6.0.2 as I've been using the same Debian/stable setup
for a while so nothing has changed much. I guess I've been using
d.font.freetype + d.text mostly, but I'm surprised none the less. In
6.0.2 it gives a segmentation fault, not a FPE.
