To clarify why this is a problem, the repo list is cached using our
normal caching mechanism so that we don't scan for repositories on every
(uncached) request.  Without this patch, only the initial request which
generates a new repo list will work and any subsequent requests using
the cached list will ignore the setting.

Of course, if caching is disabled then everything works even without
this change (guess how my test environment is set up...!).
