Short description of error
when making faces in some specific but common use cases (usually adding a new line of faces), f2 addon throws an exception. in some cases involving flipped normals and non-manifold geometry, it may also cause a crash.

Exact steps for others to reproduce the error
1:make a faced mesh
2:make a row of edges near the faces
3: press f repeatedly (the error usually occurs on the second use)
