dispatch: tolerate non-standard version strings in tuplever() (issue3470)

When developing, we may see non-standard version strings of the form

  5d64306f39bb+20120525

which caused tuplever() to raise

  ValueError: invalid literal for int() with base 10: '5d64306f39bb'

and shadowing the real traceback.
