$ cd examples
$ make font
$ libtool gdb ./font
Program received signal SIGSEGV, Segmentation fault.

0x4005b6e1 in gdk_gl_font_use_pango_font_common (font_map=0x0, font_desc=0x0,
first=0, count=0, list_base=0) at gdkglfont-x11.c:114
114 glXUseXFont (fs->fid, first, count, list_base);

fs = pango_x_font_cache_load (font_cache, xlfd);
returns NULL
Attached is a simple patch; after applygin the patch, you see
