Redmine

I have no clue why it is not working.

email notification for regular tickets is working fine.

In administration > settings > email notifications both "Wiki page added" and "Wiki page updated" are checked.

I am watching a wiki page, but when the wiki page is updated, no notification is sent out.

We are running Redmine 1.1.1, but the problem existed already before.

in the logfile there is a statement that it is sending an email, but the recepient list is empty. (I replaced some text with xxxx)
