Checking color profile error

[Revnart]

Hi, I wanted to create simple script which informs me that current document has no profile.

But I stumbled across a problem, probably simple one

Reading profile is easy:

var profile = app.activeDocument.colorProfileName;
    alert (profile);

But if document is not color managed problem occurs as I get "No Such Element" in ExtendScript Toolkit.

What can I do to check for profile and inform me that Document is not color managed?
