It seems that there is a problem with fltk. See Philip post above (he filed
it as bug #34631 in the tracker).
The problem occurs when 'too many' fltk resources are used. I could
reproduce is simply with:

for ii=1:200, figure, plot(1:10); end

At about 100 (on my machine), font loading errors are printed and octave
crashes.

I have no idea how look for the cause.
