So to be clear. You run the script and it does NOT print
'El archivo ' +filepath+ ' esta vacio'

But your file could still be empty since

Have you tried printing dbf.fieldDefs?
If that is empty then the following code will not run.
try/except is not a magic cure-all. It needs something
to trigger the exception, if you try to itertate over an
empty list that won't do it.

You should probably change the except to catch specific
errors rather than be a catch-all, but I'm not sure which
errors you might catch. That depends on the Dbf class design.
