"error on page!"

[GONUMBER6]

I keep getting errors when visiting profiles. Like my own. If I click on a tab in my profile I get the "error on page" message from IE8. But it does not happen on all profiles I visit, just some of them.

Also, a couple of my users are reporting problems viewing their profiles as well, saying they do not have any friends listed or don't see their user albums, but I can see them.

Any clue on this and what I can do to fix it?

Thank you

This is what IE8 is saying the problem is:

I cannot find a common element between broken profiles. Different usergroups, different registration dates, ect. What makes it even stranger is that if someone else visits the same profile it works. ???
