Description of problem:
I enabled the subtitle downloader plugin in Totem, but the menu entry doesn't appear in View -> Subtitles.

Running totem in a terminal, I get:
$ totem
Gtk-Message: Failed to load module "pk-gtk-module"

** (totem:12596): WARNING **: Failed to load shared library 'libcairo.so' referenced by the typelib: libcairo.so: cannot open shared object file: No such file or directory

  value = instance.get_property(self.name)

    self.manager = self.totem.get_ui_manager()
AttributeError: 'NoneType' object has no attribute 'get_ui_manager'

Closing Totem I then get:
Traceback (most recent call last):
  File "/usr/lib64/totem/plugins/opensubtitles/opensubtitles.py", line 333, in do_deactivate
    self.os_delete_menu()
