Package: python-mapnik
Version: 2.2.0+ds1-7+b2
Severity: normal
Dear Maintainer,
trying to use a Python datasource in mapnik leads to a segmentation fault. The
simplest way to reproduce is running one of the examples from the source tree
in plugins/input/python/examples/*.py.
The examples work fine on a wheezy installation with python-mapnik from
wheezy-backports
(currently version 2.2.0+ds1-7~bpo70+1)
gdb backtrace:
Program received signal SIGSEGV, Segmentation fault.
