Previously, when sending a scheduled report via email failed (e.g. due to mailbox size limits or other mail delivery errors), the error message was empty.

The actual error from the mail transfer agent was lost because the exception was re-raised without passing the original message. You now get the actual reason for the failure both in the log and in the schedule's error display.
