Not correctly displayed thumbnails.
it looks like the 500px wide preview in 8RGB is not properly decoded.
It doesn't seem to be isolated to the PowerShot S100. :-(
I think the simple solution will be to just blacklist these 8RGB previews.
I would not call it a solution, but temporarily workaround ;-)
no. it would be a solution. The bigger thumbnail is JPEG and perfectly fine.
Just to add: the RGB8 thumbnail isn't even accurate as it. Colors are off (possibly just in the wrong colorspace) and when the file is shot as "B&W" it doesn't give a B&W preview unlike the JPEG.
I actually never paid attention this, but for consistency it is better to not expose it.
