In the function "xfont_open", there's this code (line 611):
int width = font->space_width, n = pcm != NULL;
for (char2b.byte2 = 33; char2b.byte2 <= 126; char2b.byte2++)
if ((pcm = xfont_get_pcm (xfont, &char2b)) != NULL)
width += pcm->width, n++;
font->average_width = width / n;
I'm getting divide-by-zeros during redisplay, because n == 0.
Maybe this represents some degenerate condition (I'm having a hard time
reproducing it currently; I saw it happen while displaying rcirc channel
buffers), but still, it seems the code should avoid dividing by zero in
such a case.
Thanks,
