Primary & secondary tabs overlap each over

When using this theme on a page with both primary and secondary tabs, the tabs overlap each other making it very hard/impossible to use them properly:

I like the fact that the tabs are displayed to the right of the title section, but the problem occurs because they're placed there using position: absolute;.

I recommend instead creating a div around both the title and the tabs elements and use floats to align them. This will have the added benefit of allowing the div (with the rounded-corner background) to expand vertically if there are secondary tabs present.
