Yes, it is a bug.

I've got an ethereal hanging out on my desktop reminding to look into this
some more and/or file a bug report. I suspect a bug in Apache itself.

If you capture the network packets in the above example, you'll see that an
error message body is generated by mod_dav. The lines that are logged to
error_log describe it all, and note that it is a 404 error.

*However*, it seems that Apache is ignoring the 404 and/or replacing it with
a 200 in the response status line. The client gets the 200 and starts to
parse it, as if it were a proper report response. The DAV:error element at
the root of the response is flagged as an error (that you're seeing). What
*should* have happened is that the 404 comes back, and the error parser is
invoked in ra_dav/util.c. That would properly handle the error.

Something is quite broken in Apache :-( ... I also note that I got the same
error from svn.collab.net, which is a stock 2.0.44 release(!).

Not good...
