Exactly my point. There is no leak if its text or numeric.

Doesn't matter. The requirements of the protection profiles say to log the object's 
label. It does not care if its text or numeric. It also does not say sometimes or only 
when its convenient. :)  Its either important enough to log even if text conversion 
fails or its not important enough to log at all.
