django-admin makemessages PermissionError [WindError 32] and OsError [Errno 22]

[np]

Hi,

I am using custom fabric script to make .po-files for i18n.

The problem is, "django-admin makemessages" keeps on crashing. It also leaves undeleted .html.py files. I can reproduce this error also by using plain "django-admin makemessages -l pt". 

I think this problem in Windows-specific. I am using 64-bit Windows 10, Django 1.11, Fabric3 1.13.1.post1, and Windows Powershell 5.1.14393.1198.

Any help would be appreciated.

Br,

np

"Minimal working example":

 - Crashed on third try. Sometimes it complains about "locale\django.pot" being used by another process, too. Fourth try worked fine.
