I tried looking ... Hans has recently applied it and closed the bug.
Seems that a lot of activity happened this weekend!

Neither of "integrated UI" and "text edit mode" are up my alley. I
think "cleaning the undo system" as you put it, and the PROP_LIST work
seem closer to whatever I currently understand about the Dia code.
Will continue to look at those. I also have a pet project that keeps
sticking its head out ... full Gtk2 compliance!

There should be a release that concentrates on user experience and
small functionalities that can go a long way. For example, these two
bugs:

Remember last-exported file format
http://bugzilla.gnome.org/show_bug.cgi?id=439935

Popup properties dialogs should rember their last position
http://bugzilla.gnome.org/show_bug.cgi?id=481910

Default page diagram size should be taken from printer settings
http://bugzilla.gnome.org/show_bug.cgi?id=482502

Print the grid
http://bugzilla.gnome.org/show_bug.cgi?id=483749
