Not working gedit 3.8.3

[pone13]

Gnome version 3.8.4, got NoneType on tab object:
Traceback (most recent call last):
File "/home/pejot/.local/share/gedit/plugins/restoretabs.py", line 61, in on_window_show
if tab.get_state() == 0 and not tab.get_document().get_location():
AttributeError: 'NoneType' object has no attribute 'get_state'
