[Gtk-sharp-list] Strange bug

[Rafael Teixeira]

Well why are you reutilizing "this" in the autoconnects? 

You should have a diferent class for each glade window you are going to use...
That is good OO practice for a start [correctly dividing
responsabilities among objects], and is the basic assumption behind
glade#, so you need to stick to it.

HIH,
