First I will confirm that the stock script works on Ubuntu 9.10
(although it puts the links in ~/Desktop, not the current working
directory - I was briefly confused, but 'find' came to the rescue.

Yes.  Additionally, there is a comment to the effect that he intends
for the script to be easily portable to tools other than zenity if
necessary, and changing one line is easier than finding all
invocations.  Calling the variable then ZENITY is dumb, but works.  It
also makes it easier to implement types other than warning in the

That I'm afraid baffles me, and not having an 8.10 system around I
can't really troubleshoot.  Try walking through steps in an
interactive shell rather than running the script and see if you get
any useful output.

Sorry, can't reproduce that behavior on Karmic either...  Checked for
any bugs filed against zenity or metacity for 8.10?
