See CRC-110 in your support system.

A colleague today tried to create a CR on just everything that was in the repository. Not changesets, just the state of the head revision on the trunk. As we started off with an import, there's no "empty" changeset to diff against and whatever we do in the files selection screen, Crucible comes up with a nonsensical set of changes to files.

The work-around is to svn copy everything to a new branch in a single changeset and work with that, but what's the use of using Crucible's SVN interface if we have to copy over whole source trees to separate branches before we can get them into a review??
