I tried to reproduce this with ra_local and first checking out with
something like
file:///repospath/
and then switching subdir to something like
file://localhost/repospath/subdir
That gives an error with svn 1.2.4 and trunk. Can you provide a recipe?

The assert just checks that the caller knows what it's doing. The real
problem is higher up the call stack.

Was the WC in this state before starting to use 1.3.0, or does 1.3.0 allow
the WC to enter this state?

I want to look into this, but you need to describe it further. What
command triggers the assert?
