Python client and png backgrounds

I just got new client that I will be installing your product in. I setup Ubuntu 10.04, Xibo server 1.1.1, and the 1.1 python client from bzr. I setup a few layouts with different background and when the layout with PNG background cycled, the python client would stay on a black screen until I quit the program. I changed the background to a JPG and it worked flawlessly. Is there a known bug with PNG backgrounds?

The log didnt save, but here is the last bit of output from the terminal

/usr/lib/python2.6/dist-packages/PIL/Image.py:1298: DeprecationWarning: integer argument expected, got float
  im = self.im.stretch(size, resample)

Also, I noticed that the Add Image button that appears when you are changed the background of a layout does not do anything (Firefox & Chrome). Just thought I'd mention that.

Thanks,
