BUDDY: svn copy https-to-https gives "502 bad gateway"?

I've seen this pop up several times around the net, without any
resolution, so I expect it's a bug that just hasn't been logged in the
issue tracker. But I'm being a good boy and using the buddy system...

I have a simple Apache-2.0.54-based subversion repository. I've
restricted it to https only. It uses a VirtualHost domain, and sits in
the root directory of that VirtualHost. (I wouldn't be surprised if
this is part of the failcase.)

I can svn add, delete, and checkout with no problem. But when I went to
create my first tag:

svn copy https://svn.example.com/sysadmin/trunk
https://svn.example.com/sysadmin/tags/nearly-stock -m "Creating
nearly-stock tag"

I got a "502 Bad Gateway" error. Apache error log shows nothing but the
usual trouble finding "error" files. Apache access log shows:
