           Summary: at kin.naver.com 'back button' results in a blank page.
           Product: WebKit
           Version: 525.x (Safari 3.1)
          Platform: All
               URL: http://kin.naver.com/list/list_kinup.php?d1id=6&dir_id=6
                    01
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: History
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jungshik.shin at gmail.com


How to reproduce:

1. Go to http://kin.naver.com/list/list_kinup.php?d1id=6&dir_id=601 
2. Around the bottom of the page, there's a list of pages (1 2 3 4 5 6 
...). Click on one of them (other than '1') to go to the corresponding 
page.
3. If you click on '3', the url will be
http://kin.naver.com/list/list_kinup.phpd1id=6&dir_id=601&sort=kinup_point&
page=3

4. Click on the 2nd column from the left in the list of Q&A items with 
'thumb-up' icons in the rightmost column.

5. The url will be something like this:
http://kin.naver.com/detail/detail.php?
d1id=6&dir_id=60101&eid=jbyUO8ElqrWTXbxk7ObSqBSon7Nxrg8Z&l_url=L2xpc3QvbGlz
dF9raW51cC5waHA/ZDFpZD02JmRpcl9pZD02MDEmc29ydD1raW51cF9wb2ludCZwYWdlPTM=

6. Press 'the back button'.

7. The url in the address bar is 
http://kin.naver.com/list/list_kinup.phpd1id=6&dir_id=601&sort=kinup_point&
page=3

Exactly the same as what you had in step 3

What's expected:

In step 7, get the same page as shown in step 3

Actual result:

In step 7, a blank screen is shown.   

Additional info : 
IE 7 and Firefox do not have this issue. Chrome has the same issue (
http://code.google.com/p/chromium/issues/detail?id=2189 : Chrome shows HTTP 404
error page. ). So does Safari with webkit trunk build on Mac OS 10.4.11
