Hi,

here's a small patch to prevent twm from dumping core when a window
title is empty.

As I don't know how to coordinate this with the XFree86 team, I
thought it could be as well made part of bigger changes by someone
else.

So here it is; I don't intend to commit this myself as it would
unnecessarily desynchronize us from XF86.

thanks to anyone who will take this,
 Aymeric

PS: note that this applies to the XF4 part of our tree; the same patch
    should be applied to the 3.3.6 branch.
