26249	ManifestStaticFilesStorage crashes on absolute URLs	Aymeric Augustin	nobody	"To reproduce, enable ManifestStaticFilesStorage:

{{{
STATIC_ROOT= '...'
STATIC_URL = '/static/'
STATICFILES_DIRS = ['...']
STATICFILES_STORAGE = 'django.contrib.staticfiles.storage.ManifestStaticFilesStorage'
}}}

Create `a.css` in one of `STATICFILES_DIRS` with this content:

{{{
@font-face{font-family:A;src:url(/static/a.woff) format(""woff"");}
}}}

Create a `a.woff` file next to `a.css`.

Then collectstatic crashes with this stack trace:

{{{
Post-processing 'a.css' failed!

Using `url(./a.woff)` instead of `url(/static/a.woff)` avoids the issue.

It looks like `HashedFilesMixin.url_converter` doesn't handle that case gracefully, so we end up with `a.css/a.woff` instead of just `a.woff`. When a URL starts with `STATIC_URL`, perhaps it should strip it?

(I ended up with the `/static/` prefix because I set webpack's `output.publicPath` to `/static/`. I don't remember why I need it, but it doesn't make the bug less valid.)"	Bug	new	contrib.staticfiles	1.9	Normal				Unreviewed	0	0	0	0	0	0
