           Summary: Invalid parsing of backslash in url function
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: arv at chromium.org


According to http://www.w3.org/TR/css3-values/#uris

Parentheses, commas, whitespace characters, single quotes (') and double quotes
(") appearing in a URI must be escaped with a backslash: '\(', '\)', '\,'.

We unescape those escaped characters but the unescaping of \\ at the end of the
url is broken.

The following works

url("http://digg.com/?\\abc")

but this does not work

url("http://digg.com/?\\")

it never even tries to do a network request.
