good catch, although the surrounding code does not check the return values
of malloc/strdup either.

I solved it by fputs a message on stderr and exiting, since handling stdup
malloc failure by strdup'ing an error string (and returning from the function)
is like to take out a fire with matches :-) I read somewhere that malloc
failures basically should be handled by exit() since when the memory is out
the system must already be in such bad state that there is very little you can 
do.

Also that is what g_strdup (and any function using g_malloc) does.

Please let me know if you agree with such a way so that I can post
such a patch for final review.
