Error output - completion

Sorry, to post this message twice!
But I have forgotten to append the error messages in my first posting:

Hi,
I get several error outputs in the programme evoking shell from GTK+
(see below). There is so far no problem with the programme itself,
however, I would like to get rid of this outputs. How can I suppress
them?
