Bug#799473: free() Invalid pointer

[Ruben Undheim]

Seems like the last line in the error output in this bug report:

*** Error in `/usr/bin/python': free(): invalid pointer: 0x00007ffc502179e8 ***

.. is related to issue 3090 upstream for mapnik:
   https://github.com/mapnik/mapnik/issues/3090

A fix seems to have been found, and a pull request has been made there:
   https://github.com/mapnik/mapnik/pull/3146
