Gallery app asks for same image multiple times at different sizes

Bug description:
I'm seeing this with image 342 from rc-proposed.
When starting the gallery app with around 300 photos in my Pictures
folder, I just noticed the request sequence shown below. Note that all
requests are for the same image and are issued pretty much all at
once. (There is about half a second elapsed time between the first and
the last request.) The requests keep changing the size only, starting
at 342 and working their way down to 216. This is supremely
inefficient because each of the requests results in a separate scaling
operation. In addition, each of these requests ends up in the cache on
disk, so this behavior really hammers the battery and reduces cache
efficiency.
