thanks for the report, @skarkkai!

I was not able to replicate this issue. Do you recall how you were able to cause it?

I've written in a few checks (commit 97fe9b1) to try to detect this issue before it becomes a problem, but I cannot test if this actually fixes the issue or not.

Repeating the issue seems pretty easy on my system. See the attached video clip. Let me know if you'd like me to test some other version of Retopoflow.

New user, same issue for me too. Can reproduce reliably even by starting a retopo session in a new (but saved) file with a cube.

Start retopo session. Draw a stroke on the cube. Green line appears and indicates a subsequent stroke will be connected to a given nearby vertex. Clicking again at this point causes this crash for me.
