I was having this issue in Oneiric and discovered that some libraries in the deactivated PPA had been installed as dependencies for a package in another PPA. In my case, it was matthaeus123's GIMP PPA that wouldn't go away and Darktable from pmjdebruijn's PPA that had pulled in the dependencies from matthaeus123's PPA.

Try the following in Software Center:

1) Click the arrow next to "All Software" and choose the rogue PPA from the drop down.
2) If there are any packages listed with a green check mark, uninstall them. Note that this may require that Software Center remove software from another PPA be uninstalled.
3) Exit Software Center and reboot.
4) Re-install software from other PPAs that was removed in step 2.

After I rebooted, the rogue PPA was finally gone. It may be possible to avoid step 3 by using update-software-center.
