Dear fontconfig people (Keith?), I've just had a hassle involving fontconfig after importing some ttf fonts from a Windows partition. The problem is well described on various newsgroups & mailing lists but I didn't find a solution. Basically lots of gtk+ applications (ones using pango) give the error: No fonts found; this probably means that the fontconfig library is not correctly configured. You may need to edit the fonts.conf configuration file. More information about fontconfig can be found in the fontconfig(3) manual page and on http://fontconfig.prg It is widely suggested to run fc-cache again, but this didn't help me (and apparently doesn't help a lot of people who are getting the same error). Eventualy I tracked the problem down to a single font, "oldengl.ttf". Deleting this font cures the problem. I don't know if this is just a corrupt file or actually a bug in the way it is being parsed - I thought I'd pass the problem to someone who knows their way around the code! Running a pango application in a debugger to highlight where the failure is, I get to a point which shouldn't be reached (if I'm understanding correctly): ------------------------------------------------------------------ (gdb) where #0 FcCompareValueList (object=0x4099a83e "fontversion", v1orig=0x8832170, v2orig=0x887b98c, bestValue=0x0, value=0x40b51894, result=0xbfffddc4) at fcmatch.c:299 #1 0x40991679 in FcCompare (pat=0x87ecd18, fnt=0x88e0840, value=0x40b51894, result=0xbfffddc4) at fcmatch.c:374 #2 0x4099202f in FcFontSetSort (config=0x87eb5d8, sets=0xbfffdd70, nsets=1, p=0x87ecd18, trim=1, csp=0x0, result=0xbfffddc4) at fcmatch.c:673 #3 0x4099224f in FcFontSort (config=0x87eb5d8, p=0x87ecd18, trim=1, csp=0x0, result=0xbfffddc4) at fcmatch.c:744 #4 0x4084da97 in pango_fc_font_map_get_patterns (fontmap=0x874ce50, context=0x8837738, desc=0x8836088, language=0x8810d40) at pangofc-fontmap.cI:584 #5 0x4084dc96 in pango_fc_font_map_load_fontset (fontmap=0x874ce50, context=0x8837738, desc=0x8836088, language=0x8810d40) at pangofc-fontmap.cI:669 #6 0x40880928 in pango_font_map_load_fontset (fontmap=0x874ce50, context=0x8837738, desc=0x8836088, language=0x8810d40) at pango-fontmap.c:128 #7 0x4087f5e2 in pango_context_get_metrics (context=0x8837738, desc=0x8836088, language=0x8810d40) at pango-context.c:736 #8 0x405e1ca1 in gtk_entry_get_type () from /usr/lib/libgtk-x11-2.0.so.0 #9 0x00000002 in ??

I will send you the offending "oldengl.ttf" if necessary. Thanks! Pete Chapman
