<pre>I know this may be a dup, my circumstances differ.
Bug occurs 100% when using a treeview in a horizontal box that has widgets on
top of the treeview and the treeview horizontal expansion is turned off.
the widget is added to a viewport in a box in a pageview in a box in a grid in
a window, if that matters, I can also provide a tree of all the widgets and
their properties if needed. Unfortunately I can't produce an stack trace since
this is being used in a gtk# project and because of this i can't tell if the
widget is being created and the bug happens when it's added or before that.
