html parsing error

Hi!

If i open my tube in IE i get this error if a click the small exclamation mark in the left part.

Code:

---

Line:0
Char:0
Code:0
Error:HTML Parsing Error: Unable to modify the parent container element before the child element is closed (KB927917)
URL:http://www.domain.com/

---

Nothing biggy, but maybe somebody has an idea where should i look first.
Thanks!
