TreeView: Expanding any row selects first row

[Neoklis Kyriazis <neoklisk cytanet com cy>]

Hi,

I have just completed my first attempt at writing an app which includes
a GtkTreeView widget. The TreeView first shows with all parent rows
collapsed and none selected. My problem is that when I expand any one of
the parent rows, the first one gets selected. 

I made damn sure that I click on the expand handle only but the problem
is always there, no matter what I change in my code. This is puzzling me
since its always the first parent row that gets selected no matter which
one I expand.

Any help greately appreciated, this is spoiling my app!

My thanks in advance to all.
