(Oneliner patch to the function gtk_label_free_words in gtklabel.c)

This looks like a memory leak. The code just does not make any
sense to me. Whoever wrote this code should probably have a look 
at it.

I'm not really sure, I haven't noticed any memory leaking here, I just
stumbled onto this, looking for another problem.
