I just ran into this error when making a "_evw" replacement versioned view for an "_mv" versioned view. We wanted to keep both styles of version view names for testing, so I did not delete the original versioned view before making the new one with ArcSDE command line tools. This was the source of the problem. There are three triggers on the old view, but oracle was trying to make three new ones with the same name. Renaming the triggers allowed SDE tools to make the new view while saving the old one.
