I marked the current report as a duplicate of bug 857348, even if 857348
is more recent, because there are more details there.

** This bug is no longer a duplicate of bug 839712
   Plugins written in Python can no longer be enabled
** This bug has been marked a duplicate of bug 857348
   All python plugins are broken by a bad import

Title:
  Error initializing Python Plugin Loader:PyGObject initialization
  failed

Status in “gedit-plugins” package in Ubuntu:
  Invalid
Status in “libpeas” package in Ubuntu:
  Confirmed

Bug description:
  When attempting to enable any python-related gedit plugin, the plugin
  fails to load.  As an example,  trying to enable charmap throws:

  $ gedit

  Since the error is similar to the one described in Bug #839712, the plugins might be broken as a result of the last upgrade to the python-gobject package.

  The latest git version of gedit-plugins is 3.1.5, whereas the one in
  the Ubuntu repositories is 3.1.4.  So updating the package in the
  repositories could solve the issue.
