I have made a number of changes to this script over the years, the most recent,
in 2014, being to allow curved arrows. I added an entry to the registry with a
note to say that I couldn't upload the script but posted a link to it instead.
There were a number of other changes that I had made to the script before that
but I'm not sure whether or not they address the brush issue that you have.
perhaps you could try my version of the script. If necessary we could amalgamate
the changes to get a script that corrects a number of issues with the original
script, draws curved arrows and solves your problem.

I don't know of a site that hosts GIMP scripts whilst the registry is
unavailable but I am happy to replace the zip file on my site with an updated
one for the time being.

The latest version of the script:

arrows:
