[BUG] Starting Retopoflow on default cube catches exception.

[hanetzer]

Hello. I'm just giving RetopoFlow a go as an independent tinkerer who makes avatars for Chillout VR and wanna try some new stuff, so I've dl'd the version given in this repo's releases tab. I don't do commercial blender work as of this moment so I figured that'd be ok.

Retopoflow Version: RetopoFlow_v3.4.3-Github.zip or current git master fd176f7441ac7658697456b754514fe3452e2b19, cloned and symlinked to ~/.config/blender/4.0/scripts/addons/RetopoFlow

Blender Version/Hash: media-gfx/blender-4.0.2::gentoo was built with the following: USE="X bullet color-management cycles embree ffmpeg fftw fluid gmp jpeg2k nls oidn openexr openmp openpgl opensubdiv openvdb pdf potrace pugixml pulseaudio sdl sndfile tbb tiff wayland webp -alembic -collada -cuda -cycles-bin-kernels -debug -doc -jack -jemalloc -man -nanovdb -ndof -openal -optix -osl -test -valgrind" ABI_X86="(64)" PYTHON_SINGLE_TARGET="python3_11 -python3_10"

Platform Version/Distribution: Gentoo Linux, updated as of ~few days ago.

How to Reproduce:

• Install RetopoFlow
• Open blender in shell to get logs, default cube scene
• select cube, start retopoflow from active
• get the above listed exception, retopoflow menu in header vanishes, new object called RetopoFlow is created but nothing can be done with it.

Further testing seems to indicate some form of conflict with another addon. I disabled everything that was third party and it works now. I'll collect a list of the addons I use and see if that helps.

good catch! yeah, that would be super helpful to know which other add-on RF starts causing problems with. thanks
