Short description of error
Crash when calling bmesh.utils.vert_separate()

Exact steps for others to reproduce the error

  1. Open the attached blend file
  2. With the object selected, run the script.

It seems the loose vertices are responsible for the crash. I don’t understand enough about what this code is supposed to be doing (it’s extracted from an addon I’m using) but if I would expect an exception rather than a crash if this mesh is unsuitable for calling vert_separate() on.
