I am seeing the same thing with mxe-octave 4.0rc4 compiled on linux: a lot of ft_render warnings then a segfault with
imagesc(randn(10))
title('test')
I understand I need to install a font... please can someone tell me how to do that? Thanks.

At this point octave disappears and leaves a message on the commandline: octave exited with signal 11.

I would say that this represents something outside the domain of Octave. If the user has so badly mis-configured their system that not even a single font is available they need to look to a sysadmin, not to to Octave.

Ok, that makes sense. It appears the problem was always there and not related to the recent changes for TeX support. I think FLTK just fails to draw the default uimenu.
Not sure there's anything reasonable we can do about it.

Yes, here it is:

Would you be able to provide a backtrace at the "exit" call?

I'm not sure if anything can be done about this in Octave, and maybe this is a completely invalid configuration to test against, feel free to close as invalid if so. But reporting anyway since it could potentially happen on misconfigured systems and results in a variety of errors.
Testing on a system with no fonts installed, simulated by intentionally doing the following as root on my system:
With gnuplot, the following warnings and errors occur, Octave stays running:
Using FLTK, Octave simply exits after the same stream of warnings:
The last error message and call to exit(1) are in the FLTK library itself.
