17865	CachedStaticFilesStorage css rewriter should strip whitespaces from urls	Mikhail Korobov	nobody	"I have this rule in one of css files (note the extra whitespace in the url):

{{{
.b-error-page {
    background: url(../img/bg-error-page.png ) center 0 no-repeat;
}
}}}

Browsers handle this fine, collectstatic raises an exception if CachedStaticFilesStorage is used:

{{{
ValueError: The file 'img/bg-error-page.png ' could not be found with <django.contrib.staticfiles.storage.CachedStaticFilesStorage object at 0x2ee2350>.
}}}

I think css rewriter should just strip whitespaces in such cases. 

Not sure if this is relevant, but anyway:
http://www.ietf.org/rfc/rfc3986 , Appendix C: ""For robustness, software that accepts user-typed URI should attempt to recognize and strip both delimiters and embedded whitespace."""	Bug	closed	contrib.staticfiles	1.4-beta-1	Normal	fixed			Accepted	0	0	0	0	0	0
