Blender Version
Broken: 2.80 (release, Windows), 2.81 September 22, 23:12:41 - 52bdf522af (daily build, Windows)
Worked: 2.79b (Windows x64)

Short description of error

Blender crashes if to to_track_quat is called on a Vector from the Python API without arguments. This is the error message printed in the console:

Error   : EXCEPTION_ACCESS_VIOLATION
Address : 0x00...
Module  : C:\etc\blender-2.80-win64\blender.exe

Exact steps for others to reproduce the error
Run the following from Blender's Python console or text editor:

import mathutils
my_vec = mathutils.Vector()
my_vec.to_track_quat()

Additional notes
This looks to be a possible regression as running the same code in 2.79 only resulted in an error message:

Traceback (most recent call last):
  File "\test unit", line 3, in <module>
ValueError: only X, -X, Y, -Y, Z or -Z for track axis
Error: Python script fail, look in the console for now...
