Email notify fail if user have blank email field in settings

[vyt@…]

I use trac trunk from 22 april 2005 with settings

always_notify_reporter = true always_notify_owner = true

If reporter not specified email address in settings, then trac fails to send emails:

Trac[Ticket] ERROR: Failure sending notification on change to ticket #25: iteration over non-sequence Traceback (most recent call last):

I have a similar experience. This time I added a new email to the cc. I kept on getting the error until I removed the person from the cc again. However, the email was successfully send to all people on the cc list and the item was added three times to the ticket.
I am using r1724.

Traceback (most recent call last):
  File "c:\python23\Lib\site-packages\trac\web\modpython_frontend.py", line 265, in handler
    dispatch_request(mpr.path_info, mpr, env)

Maybe one more hint on the above.
I added the comment plus I added a person to the CC list. All persons where userid except for the new cc, this was an email address.

I'll take a look at this with some of the other work I'm doing on the notification.

What progress about it ?

[Emmanuel Blot]

I think this issue has been fixed in 0.10

#2729 has been marked as a duplicate. It also contains a simple patch (not sure for what version or rev though).

Does this work in 0.10 now? Need to test.

[Christian Boos]

Should be verified.

It's probably working now, but worth doing a check.
