Package: python3-wand
Version: stable (jessie)
Severity: important
Dear Maintainer,
Using python3-wand python module in python script leads to crash of the
interpreter (otherwise python3.4 is working fine).
The program crashes with message:
*** Error in `/usr/bin/python3.4': double free or corruption (!prev):
0x085048b8 ***
