I use the gedit developer plugins, source code browser, and standard
plugins. I refactored GDP to not use type and change the inheritance to
reduce the occurrences of this issue. I suspect the problem is that
libpeas encourages multiple inheritance, and that it is not clear if
pygobject creates/uses other types.

I think the issue might really be in snippets. I see in plugins/snippets/singleton.py
class Singleton(type):

Title:
  gedit crashed with SIGABRT in g_assertion_message()

Status in “gedit” package in Ubuntu:
  New

Bug description:
  This may be an issue in gedit-developer-plugins or a another enabled plugin because I have seen similar issues recently that relate to pygobject message I see in the terminal:
  TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases
  **
  ERROR:/build/buildd/pygobject-3.0.3/gi/_gobject/pygobject.c:929:pygobject_new_full: assertion failed: (tp != NULL)

  I used GDPFind to locate text in a file, I clicked the matching row to
  open the file. The file happen to already be open, I expected the
  cursor to move the the proper line. I saw the TypeError: metaclass
  conflict: in the terminal, then gedit crashed.

  PS. GDP does not set __metaclass__. Most classes inherit from object
  or a GObject class.
