I think we'd have to manually set the environment variables in a shell and launch /usr/lib/sigil/sigil via gdb manually. It may have changed, but at one time, gdb only worked with binary executables. So running the launch script (/usr/bin/sigil) with gdb didn't work.

I'll install a clean instance of Sigil with pacman on Arch later today and see if there's any problems. I've experienced some issues with that community-supplied package before in the past.
