python 3.x - Unregistring a GTK application -

-

i running gtk.application/gtk.window in python3. when running itself, shuts down properly.

i run in "ipython3 --gui=gtk3" , invoking program "%run -d xxx.py" appropriate breakpoints. when shutdown icon on window or when unrecoverable error , try restart "%run -d xxx.py", in ipython console:

> failed register: object exported interface org.gtk.application @ /org/gtk/application/anonymous exception has occurred, use %tb see full traceback. <<<

is there place can manually unregister application? (i happier documentation explaining how gnome , apps work together:). way, want app have unique instance; unregistering problem.

is there perhaps better way @ internal objects %run -d command , breakpoints?

by way, os ubuntu 14.04 64 bit.
