moveit_commander import fails after Ubuntu update

edit

I had been using the moveit_commander Python package without any issues. I installed the recommended updates on Ubuntu 14.04, which included libassimp3 and python pysassimp. A full list of updated packages is available here.

Now when I try to import moveit_commander, I get the following error:

>>> import moveit_commander
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/opt/ros/indigo/lib/python2.7/dist-packages/moveit_commander/__init__.py", line 4, in <module>
    from move_group import *
  File "/opt/ros/indigo/lib/python2.7/dist-packages/moveit_commander/move_group.py", line 40, in <module>
    from moveit_ros_planning_interface import _moveit_move_group_interface
ImportError: /opt/ros/indigo/lib/libgeometric_shapes.so: undefined symbol: _ZN6Assimp8Importer18SetPropertyIntegerEPKciPb

Any ideas on how to fix the issue? I tried uninstalling and reinstalling ROS Indigo (which is required, I can't use Kinetic), but that didn't help. Thanks!
