I use a similar zenity command in a script I've written but I don't get
this error. The difference is I specify the column contents as
parameters to the zenity command instead of reading them from stdin.
Here is my command.

competition=$(zenity --list --title="Which competition?" \
   --radiolist \
   --height=300\
   --column Select \
   --column Competition \
     TRUE  "Compex 1" \
     FALSE "Compex 2" \
     FALSE "Compex 3" \
     FALSE "Compex 4" \
     FALSE "Compex Final" \
     FALSE "Annual Exhibition" \
     FALSE "President's Challenge")


Don't know if this is an option for you, but it might help.

Regards,
Tony.
