impressive on xubuntu 14.04

I guess this bug is bugging every ubuntu user of impressive. Impressive is a presentation tool with eye candy. After installing impressive from the debian repositories, you immediately get a broken installation:

% impressive
Welcome to Impressive version 0.10.3
Oops! Cannot load necessary modules: No module named TiffImagePlugin
To use Impressive, you need to install the following Python modules:
 - PyOpenGL [python-opengl]   http://pyopengl.sourceforge.net/
 - PyGame   [python-pygame]   http://www.pygame.org/
 - PIL      [python-imaging]  http://www.pythonware.com/products/pil/
 - PyWin32  (OPTIONAL, Win32) http://starship.python.net/crew/mhammond/win32/
Additionally, please be sure to have pdftoppm or GhostScript installed if you
intend to use PDF input.

Can we fix that? Be sure that the mentioned dependencies are already installed which is required in any way.

sudo apt-get install python-opengl python-pygame python-imaging ghostscript

I fixed the script by modifying an import statement in the source code. First I looked up the source python file:

% which impressive
/usr/bin/impressive
% sudo vim /usr/bin/impressive

I modified the line which imports the TiffImagePlugin because as the error message says this is our problem. I replaced the line

import TiffImagePlugin, BmpImagePlugin, JpegImagePlugin, PngImagePlugin, PpmImagePlugin

with

from PIL import TiffImagePlugin, BmpImagePlugin, JpegImagePlugin, PngImagePlugin, PpmImagePlugin

And now my impressive installation works:
