A test program

If gtk_icon_view_set_text_column() is called a first time in a function which creates and returns a new GtkIconView, and if gtk_icon_view_set_text_column() is called again with the value -1 so only icons are displayed (no text), this error message appears:

Gtk-CRITICAL **: gtk_icon_view_get_cell_area: assertion `info->position < item->n_cells' failed

Because it's clearer with an example, in the test program (see the attachment), we have the function create_icon_view() which contains the line:

    gtk_icon_view_set_text_column (GTK_ICON_VIEW (icon_view), COL_TEXT);

And in main(), we have:

    GtkWidget *icon_view = create_icon_view (store);
    gtk_icon_view_set_text_column (GTK_ICON_VIEW (icon_view), -1);

This problem can be easily avoid if we set the text column only when needed. But it's problematic if we want to dynamically change this property.
