Bug with email Report Timespan

There is a API Call Bug while creating a Email report with a timespan:

API returned an error: Das Datum ‘2012-09-01%2C2012-09-30’ ist keine korrekte Zeitspanne. Es sollte das folgende Format haben: ‘lastN’, ‘previousN’, ‘YYYY-MM-DD,YYYY-MM-DD’

I copied the Download URL - changed the paramers to get the PDF right.

please upgrade to latest 1.9-beta which fixes the issue: 301 Moved Permanently

It’s ok for me to wait for the final version
