5.2.0 pypi release corrupted?

[xylar]

I'm seeing that the file views.py is zero bytes in size in the PyPI source tarball of 5.2.0:

$ ls -lah flask_appbuilder/views.py 
-rw-r--r-- 1 xylar xylar 0 Mar  2 15:41 flask_appbuilder/views.py

This is leading to the following failure on conda-forge:

Just a note to say that this is an ongoing issue.
