Comment 12 for bug 220656

Hi everybody, I had the same problem with my bash scripts, so I try to find out some solutions.
This is worked for me in Ubuntu Intrepid Ibex

my_app | (if `zenity --progress --auto-close --text='In progress' --title='In progress'`;
                 then
                     echo 'Job completed'
                 else
                     killall my_app
                 exit
                 fi)
