LimitRequestBody 0

This sounds a lot like 
  https://issues.apache.org/bugzilla/show_bug.cgi?id=42625
  https://issues.apache.org/bugzilla/show_bug.cgi?id=12355

But I think it is different.  I'm using certificates for authentication
to all of my pages:

<Location "/">
	# applied to _all_ URLs
	SSLRequireSSL

	SSLVerifyClient      require
	SSLVerifyDepth       5
	SSLCACertificateFile /root/openssl/doberman-ca.crt
	SSLOptions           +FakeBasicAuth
	SSLRequire           %{SSL_CLIENT_S_DN_O} eq "mcprogramming.com" and \
	                     %{SSL_CLIENT_S_DN_OU} in {"doberman", "localhost"}
</Location>

When I try to upload an image to my wiki (MoinMoin, 1.70rc2) I get 
a 413:
 Request Entity Too Large
 The requested resource
 /m17test/MyStartingPage
 does not allow request data with POST requests, or the amount of data
 provided in the request exceeds the capacity limit.
 Apache/2.2.8 (Debian) mod_ssl/2.2.8 OpenSSL/0.9.8g mod_wsgi/2.0
 Python/2.5.2 Server at localhost Port 443

I can add
 LimitRequestBody 2147483647
to conf and  things work splendidly, but if I use
 LimitRequestBody 0
(which should allow unlimited upload sizes),  I'm back to the error
messages above.

Any thoughts?  All the version info is in the error message, this is on
a debian testing system.

TIA
