I have installed the fenics package from the default Debian 8 (jessie) repository by executing the command "apt-get install fenics" (with root privileges), but cannot use it.
After running ipython (5.1.0) and typing "import fenics" results in an error: (output here). I have also tried "from dolfin import *" (in ipython too) and got exactly the same message. Trying to import the same module twice leads to segmentation fault.
What's wrong? I have Python 2.7.12+ and Python 3.5.2+ installed.
