I wouldn't bother ... you need to fix the above error, and then things 
will work. (Though I don't think it is actually occuring inside
gtk_init() ... gtk_init() doesn't do any font stuff as far as I recall.
So, I think your program is actually getting past gtk_init(). Most
likely, it's just that since your GTK+ version doesn't have debugging
symbols, gdb's output is very approximate.

If you want to step into gtk_init(), then you need GTK+ compiled
with debugging symbols, not your program.

Well, you could, but Sans needs to be a valid font. There's something
wrong about your GTK+ installation. 

 If you are using classic X fonts, there is something wrong
  with /etc/pango/pangox.aliases

 If you are using Xft1, /etc/X11/XftConfig is the relevant file

 If you are using Xft/fontconfig /etc/fonts/fonts.conf is the
 relevant file.
