Vray Clean command error

[bardo]

I've a problem when I run Vray Clean-up scene command.

it's a simple scene...with one material

Traceback (most recent call last):
  File "C:\Program Files\Blender 2.76 (With V-Ray Additions)\2.78\scripts\addons
\vb30\nodes\operators\misc.py", line 263, in execute
    debug.PrintInfo("Texture found: %s [\"%s\"]" % (n.texture.name, n.name))
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd4 in position 0: invalid
continuation byte

location: <unknown location>:-1

location: <unknown location>:-1

What's the problem?

Looks like a non-latin name of a texture.
