Hash import error

Hey Kurt,

Importing pwdump via Import file or Paste, fails with the following repetitive error shown in web2py console:

`ERROR:web2py.scheduler.localh0st#114672:    error storing result`

~12k hashes in pwdump format. Tried adding it via Paste File but Kvasir doesn't seem to take in more than 300 or so hundred hashes in one go.
