Bug ? (source same but rev changed) in Monticello

Hi

I get this when I see the changes of a seaside package on monticello.

For instances, after installing the last seaside (2.7a1-lr88)... and
scriptaculous. If I modify nothing and then look at the changes in the
same package (ie. 2.7a1-lr88), instead of havind empty, changes, I got a
long list (maybe all seaside code) with the mention (source same but rev
changed). Shouldn't it be nul ?

Thanks
