[Enrico Zini]

Package: python-djangorestframework
Version: 3.4.0-2
Severity: important

Hello,

when using rest_framework in jessie, collectstatic raises this exception:

Copying '/usr/lib/python2.7/dist-packages/rest_framework/static/rest_framework/img/grid.png'
Traceback (most recent call last):
  File "./manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)

    utility.execute()

  File "/usr/lib/python2.7/dist-packages/django/core/files/storage.py", line 201, in _open
    return File(open(self.path(name), mode))
IOError: [Errno 2] No such file or directory: u'/usr/lib/python2.7/dist-packages/rest_framework/static/rest_framework/img/grid.png'

This is because grid.png is a broken symlink:

$ readlink /usr/lib/python2.7/dist-packages/rest_framework/static/rest_framework/img/grid.png
../../../../../../../share/pyshared/rest_framework/static/rest_framework/img/grid.png
$ ls ../../../../../../../share/pyshared/rest_framework/static/rest_framework/img/grid.png
ls: cannot access ../../../../../../../share/pyshared/rest_framework/static/rest_framework/img/grid.png: No such file or directory
