See for example http://commons.wikimedia.org/w/index.php?title=Template:Description&diff=next&oldid=246447 The meaning of that link is that is shows the difference between revision 246447 and the chronologically next revision. Instead, it shows the difference between 246447 and the ''previous'' revision, 246448. Apparently the diff view assumes that page ID numbers are in chronological order, when they really aren't.
I'm pretty sure this is a dupe.
I suppose this is a duplicate of bug 2930. Sorry. *** This bug has been marked as a duplicate of 2930 ***
