            Bug ID: 209900
           Summary: [WPE][GTK] Public API should not allow trying to
                    register a special URI scheme
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit API
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: aperez at igalia.com

Calling webkit_web_context_register_uri_scheme() with a “special”
URI scheme name (like “file” or “http”) which is not supposed to
be overriden should do a check at the API entry, instead of trying
to pass that down to WebKit unchecked and cause a failed assertion:

ASSERTION FAILED: !WTF::URLParser::isSpecialScheme(canonicalizedScheme.value())
