I use Docky as a replacement for my Ubuntu task bar and noticed the deluge helper preinstalled is not comptible with 1.2.x. I spent a few hours last night adding twisted framework to it and have attached a working version.
Note this is a quick hack version with the aim to simply get it working.
Install: Docky->Settings->Helper->Install and navigate to Deluge1.2_DockyHelper.tar.
