makemessages when run for a django app and no settings will fail on settings.STATIC_ROOT and settings.MEDIA_ROOT not being set

[Carsten Klein]

In management/commands/makemessages.py it reads in line 375

ignored_roots = [os.path.normpath(p) for p in (settings.MEDIA_ROOT, settings.STATIC_ROOT)]

This will fail in situations where there is no STATIC_ROOT a/o MEDIA_ROOT, in which case ignored_roots will be populated with None, causing the subsequent path operation os.normpath(p) to fail.

This in turn will prevent users from generating the po files for django apps that do not have any such settings.

In order to fix this, the following code seems to work quite well

375         ignored_roots = []
376         if settings.MEDIA_ROOT:
377             ignored_roots.extend([os.path.normpath(p) for p in settings.MEDIA_ROOT])
378         if settings.STATIC_ROOT:
379             ignored_roots.extend([os.path.normpath(p) for p in settings.STATIC_ROOT])

Duplicate of #23717.
As you can see, your 1.8 version is several months old...

Oh, great I did search for makemessages / django-admin but did not search for closed issues as well...

You will get a new release with pip install --pre ...
