Torbutton Disables Clear Fields

Clear Fields buttons are not visible with Torbutton 1.2.4 enabled. I confirmed this by disabling the Torbutton add-on and replacing the clear fields buttons on the toolbar. Reenabling Torbutton again makes the CF buttons disappear.
I did this twice, just to make sure.

System info: Firefox 3.6, Kubuntu Linux 9.10.

(This editor doesn't wrap the lines. I put hard carriage returns in..)
