Bug#988090: planned removal of db5.3 will break python's dbm.ndbm and therefore apt-listchanges

[Matthias Klose]

correcting ...

dbm/ndbm will be shipped, but based on gdbm-compat, in the python3-gdbm package.
The on-disk format of the generated database is likely incompatible with the one
generated by the db5.3 backed _dbm module.
