No, you could also detect a software error -- for example, if
Subversion were writing out revprop values *or their checksums*
improperly. Or it might be trying to write something else, but due to
boundary bug accidentally smash part of a revprop value or a revprop
value's checksum. So it's technically possible for a Subversion
problem to be detected by this means.
It's not only hardware that makes mistakes :-).
