Djangos builtin server trying to implement self hosted font

Question

I have a problem concerning Django and custom fonts.. Which way ever I try to use a custom font of this type

@font-face {
  @font-face {
    font-family: 'abc';
    src: url('abc.eot');
    src: url('abc.woff');
    src: url('abc.ttf');
    font-weight: normal;
    font-style: normal;
  }
}

or this type

@font-face {
  @font-face {
    font-family: 'abc';
    src: url('abc.eot');
    src: url('abc.eot?#iefix') format('embedded-opentype'),
      url('abc.woff') format('woff'),
      url('abc.ttf') format('truetype'),
      url('abc.svg#cde') format('svg');
    font-weight: normal;
    font-style: normal;
  }
}

Django's builtin server ("python manage.py runserver") is printing

Traceback (most recent call last):
  File "C:\Python34\lib\wsgiref\handlers.py", line 137, in run

    now = time.gmtime(timeval)
OSError: [Errno 22] Invalid argument
"GET /this/is/the/correct/path/customfont.css HTTP/1.1" 500 59

it does not matter if I link the customfont.css via <link>, copy&paste the content into my base.css (which is loaded correctly) or embed it into the .html file with <script>@font-face..</script>. I tried different fonts, too.

Excerpt from my settings.py:

DEBUG = True
LANGUAGE_CODE = 'en-us'
TIME_ZONE = 'CEST'
USE_I18N = True
USE_L10N = True
USE_TZ = True

even though I am not using anything besides DEBUG = True by now. My machine is running Windows 8 64bit if it matters.

Any ideas anyone? Ty

It looks like the problem is in the "last modified" value on the file itself. Possibly the file was created on a computer with an offset clock, or some such.

Ref:

• https://code.djangoproject.com/ticket/15120
• Why am I getting 500 errors when serving web font files in my CSS?

Try updating the file with the following command:

copy /b customfont.ttf +,,

(That's a Windows equivalent of *nix "touch" command, ref: https://superuser.com/a/764721/66285 )
