"Debian Stable should not be combined with other releases. If you're
trying to install software that isn't available in the current Debian
Stable release, it's not a good idea to add repositories for other
Debian releases. The problems might not happen right away, but the next
time you install updates." [1]

Fortunately, a later version of weechat is available from
debian-backports.[2] That would be a much safer choice.
