svnadmin hotcopy losing revprops

[dpm]

I'm using svn 1.8.4 on RHEL 6.3 (we're in the process of trying to upgrade from svn 1.6 to 1.8).
However, the svnadmin hotcopy command doesn't appear to be working correctly with the
repositories I've copied over from our 1.6 server - most of the db/revprop directories are missing.
See output below.
It works OK if I upgrade the repository first.
Am I missing something obvious?

Thanks

Please wait; upgrading the repository may take some time...

Upgrade completed.

Thanks for your response (although it doesn't seem to have made it
to the archive yet - perhaps because I used google groups?).
It's good to know that the problem is reproducible.
I'll go back to using 1.8.3 for the moment.

Do you think this bug needs advertising more widely somehow?
Our backup procedure relies on hotcopy and, if I hadn't discovered
this during my testing, we could have ended up having no useable
backups which is a scary thought.

Thanks,
David Matthews

Yes, my reply went to google groups and was bounced because I'm not
subscribed to the google group.
