I might have been drinking too much lately since the assertion is in
your program, not in fontset.c in a lib :)

Now we have to understand why the code at the URL below returns NULL:
http://git.debian.org/?p=pkg-xorg/lib/libx11.git;a=blob;f=src/FSWrap.c;h=10634ceecae26eab5306507cadda2181019ae2be;hb=HEAD#l167

That would be either XOpenOM returning NULL, or XCreateOC returning
NULL, or list->charset_list && *missing_charset_list == NULL...
