I overwrote the SQL handler late one night and lost about 30 minutes work and being tired (hence the overwrite in the first place) I released without fixing it.
The make test (which ran fine) didn't catch the problem because it doesn't test any of the handlers. So now I have added a minimal test suite. This should also make resolving installation problems somewhat easier.
Anyway version 1.6 of autodia is at the site and winging its way towards your nearest CPAN mirror.
