problem with ajax tabs in jquery-ui 1.8 and jquery 1.5

problem with ajax tabs in jquery-ui 1.8 and jquery 1.5

I try to use ajax tabs based on the example from the documentation as shown in http://jqueryui.com/demos/tabs/#ajax.

I'm using jquery-ui 1.8 in combination with jquery 1.4.4 it works, but it's not working when using jquery 1.5 (which is included in debian wheezy).

Is this a bug or has anything changed in the way to using ajax tabs ?
