Win 10 x64 / nVidia GTX 780 with latest drivers

Blender Version
Broken: 2.78.4 Hash: 411836d
Worked: Official 2.78a

FBX import works as expected but as soon as I try to import the same FBX or a different one Blender throws this error:

`Traceback (most recent call last):

File "H:\blender-git\build\bin\Release\2.78\scripts\addons\io_scene_fbx\import_fbx.py", line 2252, in load
  elem_root, version = parse_fbx.parse(filepath)
File "H:\blender-git\build\bin\Release\2.78\scripts\addons\io_scene_fbx\parse_fbx.py", line 184, in parse
  init_version(fbx_version)

  assert(_BLOCK_SENTINEL_LENGTH == ...)

AssertionError`

Repro steps:

Open Blender
Import > FBX any FBX you like (a simple cube does the trick). The source of the FBX doesn't matter. Even FBX exported from Blender cause the issue
Everything should work and the geometry is imported
Repeat the very same and import the same (or a different) FBX
Blender throws an error and doesn't import anything
You will have to restart Blender to get the importer working again.
