Wouldn't it be possible to use a different directory, e.g.
"mail/local-index/folders.db"? That would avoid both problems.

Right. For me, folders.db showed up as having 7 unread mails in it. The
mbox parser probably found some satisfactory ^From occurrences. It also
made local mail unusable, since it would constantly throw errors and
fail to update vfolders (details are a little bit foggy at the moment,
but I remember being hindered to the point of not being able to read
mail).

Ok, if I can just remove the old indexes/summaries, I'm happy :)

I still think relocating folders.db is a better option, since it would
work for everyone without necessitating an upgrade.
