Yeah, it's a BadFontFormat (88). The (*scalable->renderer->OpenScalable) call is returning the BadFontFormat. Enabling DEBUG_TRUETYPE in ft.h (and fixing the XLFD printing bug) printed out: Open Scalable /System/Library/Fonts/ZapfDingbats.ttf, XLFD=-misc-zapf dingbats-medium-r-normal--0-0-0-0-p-0-iso10646-1 Closing face: /System/Library/Fonts/ZapfDingbats.ttf Error during load: 88 So it's happening inside FreeTypeLoadXFont which in turn got it from FreeTypeLoadFont which in turn got it from FTPickMapping. gdb is being a PITA and not finding debug symbols, so I can't step through, but it looks like something in FTPickMapping doesn't agree with the font. _______________________________________________ [email protected]: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: http://lists.x.org/mailman/listinfo/xorg-devel
