Thanks for the feedback. I guess the "[[ -v ... ]]" to check if a variable
is set, must be syntax new to bash 4.2.

For bash 4.1 compatibility you would have to change line 33 to:

    if [[ -n "$curtype" ]]; then  # Called from _gst_launch

However, the script as it currently stands uses functions like
_init_completion only available in bash-completion >= 2.0. Give me an
evening or two to make this backwards-compatible for you. :-)

Dave.
