While trying to produce a smaller testcase, I changed the
dovecot-virtual file to

mbox/*
      all

and the problem went away. It did not reoccur after reverting the
change. After this, I also could not reproduce the problem on a copy of
the Mailbox, which I produced using cp -rl. Probably I should not have
used hardlinks there.

So this sounds like a chaching-related problem to me?  Hm, I remember I
renamed the virtual folder yesterday (in the filesystem, using mv).
