The code is in "proc getentry" in nstrace.

Actually, one should only access the value ::errorInfo and friends 
immediately after an error occured, that is typically within a catch 
clause. "proc getentry" seems to try to preserve the previous 
::errorInfo and ::errorCode settings (not sure why). I think the access 
to ::errorInfo should be guarded by an "info exists".

Will try this later and do some testing.
