Is this a bug in the cache cleanup stuff?
When I push to screened (which has a now invalid entry in sources), I
get
HINT: I could not reach the following repository:
/home/darcs-unstable/submitted
If you're not using it, you should probably delete
the corresponding entry from _darcs/prefs/sources.
Push successful.
The entry is in the remote end, which is why this seems a bit odd.
