I'm not sure if there are really bad paths in the database, or notmuch
is just handling illegal search syntax badly. To quote
notmuch-search-terms(7):

   The directory must be specified relative to the top-level maildir
   (and without the leading slash).

Please try with correct search syntax in order to narrow down the
problem.
