#FIXME: Workaround for LP: 1315866
# This happens due to the fact that when a Python dict is garbage
# collected the order in which the individual items in the dict are
# garbage collected is unpredictable, causing the dtor's to be called
# after python exits. In order to work around the issue, upstream
# suggested that projects disable the automatic destruction of C++
# instances and C structures
# Ref: http://www.riverbankcomputing.com/pipermail/pyqt/2014-March/033929.html
