The above was my line of thinking as well. The working copy contains
pristine copies of all files, but those files won't necessarily all
be at the same revision; it is usual for a working copy to be in a
mixed-revision state -- it will be unless an svn update was done on
the root of every working copy before the crash, which I imagine is
unlikely to have occurred.

In order to submit changes to the repository, Subversion constructs a
diff between the pristine local files and the changed local files. If
the pristine local files at those revisions don't match what the
server thinks they look like in those revisions, then the diff that's
sent to the server won't make sense, and who knows what will happen.
