[PhotoFloat] python ValueError: time data '0000:00:00 00:00:00', does not match format '%Y:%m:%d %H:%M:%S

I have received this same exception stack on a handful of images (which I can only guess is due to faulty exif data).  The patch works just fine, but are there any plans to add this patch to the repo or is there another suggested solution?  Thanks, and I love PhotoFloat, please keep up the great work!
