[Tabs] UL in Tabs plugin

Hi all,
i use the tab plugin with much pleasure! Only i have one problem with
it. I have an UL in a tab. The plugin styles this UL as if it's part
of the tab UL.
I use at the moment:
$("#tabs > ul.tabs:first-child").tabs();
for initiating the tabs, but
$("#tabs > ul) or
$("#tabs ul.tabs) or
$("#tabs ul) won't do the trick.
Can anyone help me?
