Purifier module causes error

Hi!

I've downloaded Purifier from https://github.com/gallery/gallery3-contrib.

When I put it into Gallery3 directory and try to go to modules configuration Gallery3 log me out and there is an error in the log:

Any clues?

That was supposed to be funny? If you really need this: yes, I know where to put modules.
