All righty...

we only see those for the "public" URLs.

[ these values come from mod_dav.h ]

It should not be a type 1. Anything under the ../$svn/wrk/ area should be
DAV_RESOURCE_TYPE_WORKING, whether it exists or not.

mod_dav_svn is the guy that labelled it incorrectly.

Hmm. I don't see anything obviously wrong in the parsing and setup. It all
happens in repos.c. dav_svn_parse_uri() does some initial parsing
(indirectly using the dav_svn_parse_working_uri function). After the parse
is done, then it calls the dav_svn_prep_working() function. Neither of those
can set the type to REGULAR.

That would tend to indicate something else is going on somewhere... Some
debugging is in order.
