This trace isn't valid. Did you compile DirectFB with -O3? It usually
makes back traces useless...
Good point. I have re-built DirectFB with -O0 and this gives a different
(hopefully more accurate) trace:
Program received signal SIGSEGV, Segmentation fault.

There are still holes in it, but I don't use gdb often so I'm not sure
if this is "normal". ;)
Is there any debugging output I can enable from DirectFB (especially the
matrox driver) which will help?

James.
