Plugin crashes on ubuntu gnome 15.10

[Przemek]

Plugin doesn't work. It crashes on opening .tex file. Traceback speaks for itself. No plugin functionality is available.

Traceback (most recent call last):
  File "/usr/lib/gedit/plugins/latex/appactivatable.py", line 58, in do_activate
    self.add_latex_menu()
  File "/usr/lib/gedit/plugins/latex/appactivatable.py", line 63, in add_latex_menu
    self.menu_ext = self.extend_menu("tools-section")
AttributeError: 'LaTeXAppActivatable' object has no attribute 'extend_menu'
Traceback (most recent call last):
  File "/usr/lib/gedit/plugins/latex/windowactivatable.py", line 201, in _init_actions
    self._main_box = self.window.get_children()[0].get_children()[0].get_children()[0].get_children()[1]
IndexError: list index out of range

Could not find place for the toolbar. Disabling toolbar.
TypeError: _on_load() takes 2 positional arguments but 3 were given

System:
Ubuntu Gnome 15.10

Status changed to 'Confirmed' because the bug affects multiple users.

Fixed (long time ago). This bugtracker is not used by the plugin maintainers. Please report bugs upstream ( https://gitlab.gnome.org/GNOME/gedit-latex/-/issues/ ).
