I tried new version. The X11 server that formerly crashed, now gives a warning about unavailable fonts.

I've made a change to prevent font sizes smaller than or equal to zero, this might fix it! 

Could you check the latest CVS?

Latest CVS, that doesn't fix it.

If I shrink the font.
** ERROR **: file main.c: line 271 (set_fonts): assertion failed: (m_r_font && m_b_font) 
aborting...


That has to be something to do with your font name.
I've checked in a bugfix, which checks that the font loading was ok, before applying the font to the screen. 

This should fix your problem, please have another try with latest CVS now.
