Yes get 3.6.7, but; if you use widget names that are unique within
toplevels, you have to be careful of how you use that with GtkBuilder,
dont feed it the entire Glade file at once; instead specify which ones
you want to build - I think the policy right now for GtkBuilder is
unique names throughout the builder instance - so you may also
want to be carefull to use separate GtkBuilder instances to build
separate parts of your project.

Note: if you have a widget naming glitch with Glade 3.6.3, then
toggle the policy property in the preferences, this will actually
modify the project (it creates an undo item) and fix any duplicate
names if found (you shouldnt have any such glitches with 3.6.7
though).

Cheers,
      -Tristan
