Thanks for answer, Thomas.
Problem is that exception is rased but not handled in RB in block try - 
catch, it proceeds further and I see error dialog: "NilObjectException 
was not handled. App must shut down".
Also this exception may be caught in App.UnhandledException event, but 
not in that try - catch block that I want for proper error handling. But 
in some places exceptions are caught
always. I can't now understand reasone of  this difference.
