I see two possibilities to fix that.

The first one, is to disable the properties that make
it crash (either by putting <Property
Id="headers_clickable" Disabled="True"/>, either by
putting its setter and getter to ignore).

The second one is to add a new PreCreate function that
sets a model for the tree (it still doesn't exist any
PreCreate function, so the code that parses this part
of the xml should be modified to add a new PreCreate
tag).

The second option has the benefit of making it
possible  to have an example tree that can be edited
in glade.

To synchronize the glade vision of properties' values,
and the real properties' values.

If you change the default value of a property in the
xml file of a widget, glade's GladeProperty will be
created with this default value, but you still have to
set the property in the widget itself.

PostCreate functions assume that these values are
synchronized.
