Comment:

 I found the problem.  It's not invalid, but by all means feel free to
 'wontfix'.

 Any time an image is uploaded, if that image was saved in the Adobe RGB
 color space, then the image does not get loaded correctly for resizing.
 Thumbnails are saved in the default color space, which is sRGB.  By
 failing to perform the color conversion, and then failing to specify the
 non-default color space in EXIF, thumbnails are produced with colors that
 are noticeably different from the original.

 The real annoyance here is that many programs, including web browsers,
 don't read the EXIF color space in the first place.  In the web browser,
 thumbnails are rendered the same way as the original, which also appears
 to have the wrong colors.

 On the other hand, this problem can become very obvious when surfing
 through the uploads directory with a program like Windows Picture and Fax
 Viewer, which does render the original image correctly.
