I just tried this and it doesn't work. I set the first column as resizable in the main.ui (through Glade) and the bad behavior is still present. Of course, the sizing of the column is also marked as "AUTOMATIC", which may be the reason why. I am assuming that it works for you because you are overriding the "AUTOMATIC" sizing by calling gtk_tree_view_column_set_resizable() after the UI has been processed.
