TypeError

[muranyia]

  File "/home/muranyia/.local/share/gedit/plugins/sessionsaver/__init__.py", line 164, in on_manage_sessions_action
    SessionManagerDialog(self, self.sessions).run()
TypeError: __new__() takes 1 positional argument but 3 were given

Gedit 1.10.4, Ubuntu 14.04.1

Changing line 54 in dialogs.py to:

def __new__(cls, *args):

solves the problem.
(Line 56 is not to be touched).

Pull Request #3 is the same as this issue. Since it hasn't been merged yet, you have to apply the patch manually.

I ported sessionsaver from an updated gedit-plugins and created gedit-plugins-sessionsaver rpm for CentOS 7 if anyone is interested.
