Some thumbnails (for now I could only find [[commons:File:Jan_hoet.jpg]] are negative.

Comment 2 Bawolff (Brian Wolff) 2011-02-24 20:26:35 UTC
Both affected images are:
*CMYK images
*Have the exif color space tag set to uncalibrated (65535=uncalibrated)

Thus, sounds like upstream issue/dupe of bug 24854.

In the mean time, maybe convert to rgb, and re-upload.
