'this.handle.unwrap("a").mouse is not a function' when destroying a slider


When I destroy a slider, I get the error
'this.handle.unwrap("a").mouse is not a function' in ui.slider.js,
line 49. Am I doing something wrong, or have I found a bug?
Some background:
I've created a slider and created a callback for the slide event that
updates a value on my page. I've got a call to $.ajax() that results
in the containing div for the slider (great-granparent) having it's
html assigned to a different value. It appears that this causes $
("#mySliderLocation").slider('destroy') to be called, and then I get
the error described above.
Any ideas? Have I missed a faq somewhere?
Thanks,
