[Typo3] JSmenu not working - gives "no properties" error

[Peter Kindström]

Hi list!
I moved my old web pages from a 3.7.0 site to a 3.8.0 site by
using "Export/import .t3d". And suddenly my JSmenu doesn´t work
in the new 3.8.0 environment! I use TemplaVoila 0.4.0.

The selector box (JSmenu) shows alright (see below), all the
expected items are there and I can choose an item. But after I
have choosen an item, nothing happens except the error message.
The same appears both in Firefox 1.0.4 and IE 5.5.

You can test it at:

I have checked my template and TypoScript I can´t find any
error. Am I missing something or is this a bug?
Can anyone confirm that a JSmenu like this works/does not work
in Typo3 3.8.0. with TemplaVoila 0.4.0?
