How to patch Abiword in XUbuntu

I'm a developer migrating to linux from mac. Just installed XUbuntu on my
new ASUS 1015E and I'm seeing the scrolling bug in Abiword that seems to
be a pretty common problem. However, like this user:
Mouse scrolling bug in Abiword and Open Office
...I'm brand new to linux and I can't figure out how to patch it. Here's
the link to the bug report:
https://bugs.launchpad.net/ubuntu/+source/abiword/+bug/960089
Could someone please direct me to how to install the patch OR downgrade to
Abiword 2.8.6? (the software center doesn't seem to offer a downgrade, and
I tried installing according to these instructions:
http://abisource.com/wiki/Install_on_Ubuntu
but still got 2.9.2)
