So I fixed it. You can get the new Arrow Designer 0.5 on my GIMP Arrow Designer page.
It's purely a coincidence that I discovered this a week before
SCALE, where I'll be speaking on
GIMP Scripts and Plug-Ins.
Arrow Designer is one of my showpieces for making interactive
plug-ins with GIMP-Python, so I'm glad I noticed the bug when I did.
