Python Client dies on Ubuntu 9.10 showing Interlaced PNG files

[Alex Harrington]

Attached image causes client to freeze on a blank layout (assuming one region with this image in it).

Problem is uncaught exception in:
http://bazaar.launchpad.net/~alexharrington/xibo/pyclient-1.3.1/view/head:/client/python/plugins/media/ImageMedia.py#L44

Marked won't fix as Ubuntu 9.10 is no longer supported.
