This is quite strange, because the db really should have that statekey
in there.  You could simply try removing that line from sb_dbexpimp.py
and looking at the file produced.  If it looks right (i.e. a '`'
separated file filled with lots of ham/spam counts), then keep going,
otherwise report back.

This is the expected error when trying to open a pickle as a dbm, as in
this case.  IOW, -D is right, even though it's opposite to the other
scripts (sigh).
