Not sure if it's related, but I noticed that many of the CloudMade
extracts can't be processed using osmosis (even though they're
generated with osmosis), except for the operations that don't try to
validate the order of elements.  It seems they often contain
consecutive elements with the same id, but possibly different version.
 I have a little patch (attached) to add a new filter (--ff) that
"flattens" the file.  It does the same operation on sorted entity
streams as --simplify-change does on change streams, unfortunately
"--simplify" is taken by a different operation now.  I decided it was
faster to modify osmosis than to download the planet and make my own
un-broken extracts.

Cheers
