It doesn't look likely given the code, but I couldn't rule it out.
Does this reproduce with KPA 5.3?  If not, can you bisect to the
change at which it does happen?

Given that the behavior sounds like it's nondeterministic, it's just
possible that my performance changes did this.  In which case I'll
need a set of photos that exhibits this behavior, even
non-deterministically.
