I was thinking that this is a bug in GAIL. 

Calling gtk_label_set_mnemonic_widget() causes a notification of a change in the 
property "mnemonic_widget". GAIL should be able to set up an emission hook to 
listen for such notifications and when one is received, determine what the 
mnemonic widget is and cause the relation LABELLED_BY to be created.

If you agree with this approach I can add this functionality to GAIL.

This sound OK to me. I am sure if Marc Mulcahy thinks differently you will hear 
from him.
