I installed the software firewall GlowWorm on my G4 Powerbook running OS X 10.5.1. It hosed my system something fierce; don’t do it. Everything froze, and I had to cycle power to reset the machine. Subsequently the machine would not restart normally. I had to reboot in safe mode ( first time ever) and then uninstall GlowWorm. Fortunately, there was an uninstaller in /Library/Application Support/GlowWorm/utilities.
BTW, safe mode took about 15 minutes to come up, so give it time if you find yourself in this situation.

Just tried to do what you did on 10.5.2. Same result. I was about to reinstall my system when I came across your post. Thanks!

The developer clearly states that GlowWorm does NOT work with Leopard.
BTW, the same problem can occur with Little Snitch if you use AppleJack. Some errant kext file will kill your system.
Also, Apple advises against using Application Enhancer for the same startup reason.

Evidently some people missed that warning.
