Description:
       When employing tab-completion with bash_completion on a terminal 
emulator, the message "grep: write error: broken pipe" is output to 
stdout. The completion works, and the spewed text does not affect the 
command.

Repeat-By:
       Typing a partial command or path and using tab-completion in any 
number of terminal emulators under gnome 2.4/Debian.
