can't switch lightweight checkout if base branch was renamed

[Alexander Belchenko]

If I rename/move base branch of lightweight checkout then I can't switch checkout to update base
branch location:

C:\work\Bazaar\plugins\qbzr>bzr switch C:/work/Bazaar/qbzr-repo/trunk
bzr: ERROR: Not a branch: "C:/work/Bazaar/qbzr-repo.packs/trunk/".

So every time I need to manually update .bzr/branch/location file. And then everything again works.
It's boring and does not sound right.

Is this inability to switch lightweight checkouts is intended behavior (by design) or just missed
feature? Should I file a bug about this?
