Hmm, what's a "keyboard callback" mean in this context?
To read the keyboard you usually have to setup a handle()
to trap events, unless I'm forgetting something. Or maybe
you've got keyboard shortcuts enabled for certain menu items,
but that should trigger the same callback as the mouse, so
it'd be odd if one worked and the other did not.

Hard to tell from the code you've posted, as it's missing what's
going on in the callback and menutable, which is where the problem
likely lies.
If it crashes, it might be the menutable isn't NULL terminated
correctly..
or the callback is doing something it shouldn't with the widget or
userdata
pointers.
Building the menutable is a careful business to do manually -- usually
I only let fluid handle building menu tables, as submenus need special
extra NULL terminations, IIRC.
I prefer to use menubar->add() to build a menubar in contexts outside
of fluid, eg:
menubar->add("File/Save", ..);
menubar->add("File/Save As", ..);
menubar->add("File/Quit", ..);
menubar->add("Edit/Copy", ..);
For more info, see this example:

BTW, since this is most likely a non-opengl issue, it's better
to use fltk.general for this kinda stuff; you'll get more replies,
and the back+forths will be more useful to folks on that group.
Try running the debugger to see where it crashes..
