Sendmailpipe not working after upgrade to 3.8.12

Hi.
I just upgraded our RT install from 3.8.10 to 3.8.12. After this RT was unable to send e-mail messages with the default outgoing mail setting (sendmailpipe). I change mail command to sendmail (and removed -t from mail arguments), and then it works.
In the logs it looks like it was trying to use sendmail even before I changed it, but with the -t option?

Errors in apache error log:

Hi.

I just upgraded our RT install from 3.8.10 to 3.8.12. After this RT was
unable to send e-mail messages with the default outgoing mail setting
(sendmailpipe). I change mail command to sendmail (and removed �t from
mail arguments), and then it works.

Update to 3.8.13

Hi.

Thanks for that. I had missed that 3.8.13 had been released since I flagged the release notification for 3.8.12 in my e-mail client.
