gedit-plugins unable to load

[Alex Schiff]

When I try to enable some plugins in gedit, I get an error:
The plugin 'Bracket Completion' could not be loaded
An error occurred: Plugin loader 'python' was not found.

If I run from the command line, I get:
(gedit:4374): libpeas-WARNING **: Error initializing Python Plugin Loader:PyGObject initialization failed
ImportError: could not import gobject (error was: '/usr/lib/libpyglib-gi-2.0-python2.7.so.0: undefined symbol: _Py_ZeroStruct')
Error in sys.excepthook:
