The label will only request size for the ellipsis if you dont manually
set a size request - you could just use a value...

...or... if you want an expand to fit label... I dont know if this is
documented anywhere
but just take a look at the size_request() and size_allocate_after()
functions here:
http://svn.gnome.org/viewvc/glade3/trunk/gladeui/glade-editor-property.c?revision=2034&view=markup
(note the calculation for the child label allocation will be alot
simpler if you just wrap it alone
in an hbox or something).

Its a little evil and hackish but the technique will give you expand to fit
allocation ellipsis (although personally I've only tried it for word wrapping).
