Thanks for the feedback Nickolay.


  Unfortunatly, I am not mandated to work on gtk+ by my employer.  I 
will live with this shortcomming.  Also, I am using gtk+ within python 
and the ensure_layout() function is not available in this language (or I 
did not find the function on the gtkLabel object).

  I checked bugzilla, but found no opened bug relating to this.
