           Summary: Local storage getItem() for an empty string returned
                    UNDEFINED value.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: HTML DOM
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: naveenbobbili at motorola.com

1. Use the following code:

<html> 
    <head> 
        <script> 
            console.log(localStorage['test1'] + "|"+localStorage['test2']+"|");

            localStorage['test1'] = "hi";
            localStorage['test2'] = "";
        </script> 
    </head> 
    <body>

    </body>
</html>

2. Load webkit gtk browser and on first visit it reads "undefined|undefined" in the console. Reload and you get "hi||".
3. Restart browser and it prints "hi|undefined".

What is the expected result?
I would expect it to continue to log "hi||" after browser restart.

Analysis:
This issue has occurred as a result of fix provided to https://bugs.webkit.org/show_bug.cgi?id=58762
Blob datatype return NULL even for empty strings. So this needs to be specially handled in StorageAreaSync code.
