Re: Hmm looks like gtk_tree_store_remove is broken?

[Mikael Hermansson <tyan linux se>]

Forget this bugreport it was an stupid error in my code.

The routine was connected to "expand_row" signal.
And everytime I expand the row I wanted it to remove childnodes 
and insert the "fresh" nodes.

But I forgot i needed to call gtk_tree_view_expand_row manually
after new insertion of nodes.
