           Summary: Crash during conversion of element to QVariant
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: allan.jensen at digia.com


KWallets integration QtWebKit causes crashes on entering a number of webpages.

The backtrace goes through convertValueToQVariant and in a normal backtrace looks like it ends in OpaqueJSString::identifier. When compiled with more debugging info though, the crash does occur somewhat deeper but is still triggered by what happens in OpaqueJSString.

The problem seems to be the construction of an Identifier containing a null-string, which is invalid.
