Sorry, I didn't investigate how old it is.

The earliest tag with this commit is xorg-server-1.12.99.901. You could see
that by running "git describe --contains 749a593e". The commit hash is
mentioned in the last bug comment on bugs.freedesktop.org.

I assume the only real release including this fix is 1.13.0.

I didn't notify neither Debian nor Ubuntu. It would be good to do so.

Sincerely,
