When uploaded two images (http://en.wikipedia.org/wiki/Image:Java_source2.png, http://en.wikipedia.org/wiki/Image:Java_source.png), it has problem with thumbnailing. It has shifted down a bit and replaced parts of the image with transparent whitespace.
After testing reducing colordepth from 16bit to 8bit, no visible change occured.
We (me and brion) have concluded tha the option -trim in imagemagick is the source of the problem
Specifically, interaction between -coalesce and the way the image's coordinates are left from the source image's -trim.
I tested this, and it seems this issue on longer exists.
closing since no one still thinks it is broken... reopen with an example if you think it is still broken.
