Can you reproduce this issue with nx-libs 3.6.x (please build it from source).

In nx-libs we lately dropped nx-X11/lib/font completely and now build  
against the libXfont.so from X.Org. As the issue causing function is a  
libXfont function, I presume this issue to be solved in nx-libs 3.6.x.

Any feedback is highly appreciated.

Mike
