Probably not, but it depends on the which database you used to make the
shelf. By making sure that dumbdbm is used both when making the shelf
and when reading it, it should be possible. The default way of creating
and reading a shelf will not work though (as you have seen yourself).

Instead of using shelve.open(..) try instead:

   import shelve, dumbdbm
   shelve.Shelf(dumbdbm.open("file"))
