[pygtk] Problems with gtk.TreeIter and reorderable gtk.TreeView

[Damián Nohales]

Hello there!

I have a gtk.TreeView using a gtk.ListStore model, which is a list of 
music tracks. I've setted the "reorderable" property to TRUE in the 
gtk.TreeView object and I'm using a gtk.TreeIter to save the current 
playing item, called "current_track".

Well suppose that I have 5 music tracks on my list and the second track 
is playing, so the path associated to "current_track" when I use 
"model.get_path(current_track)" is (1,). When I drag the first element 
below the second, now "current_track" path is (0,), but, when I drag the 
row associated with "current_track" (now the first row), to another 
position, the path of "current_track" is None.

Is this the normal behavior or am I doing something wrong?

Thanks!
Regards!!
