Comment 44 for bug 25827

I've written a thumbnailer bash script, that uses imagemagick if it's installed, if not, totem-gstreamer-video-thumbnailer. Unfortunately, the latter puts "film strips" or "film rolls" in the image, giving the user the impression that the file is a video, not a document. Any one know how I could disable this behaviour? Is there another program that's installed by default that I could use? evince-thumbnailer unfortunately keeps the transparency in the image.
