Just to clarify the issue: this leak is present if the plugin is
written in python (and compiled to a loadable bundle using py2app) and
loaded into an Objective-C app. The leak does not occur if the plugin
is loaded into a Python app. This issue was first described in bug
#1982104 (http://sourceforge.net/tracker/index.php?func=detail&aid=1982104&group_id=14534&atid=114534).
