see the gray space on the left side

I test konqueror in kde 4.1.2 (kubuntu packages ). I find some improvement in this problem. Now, the gray space appears when I open new tab and it disappears when the konqueror finish download the page. 

One step in right direction to solve this problem. 

SVN commit 869761 by ggarand:

- fix incomplete repaints happening from time to time
  when jumping early during page load. (#166413)

- various RTL layout application (-reverse cmdline option) fixes
  . implement RTL scrollbars on CSS containers
  . fix iframes scrollbars in RTL mode
  . fix wrong direction when scrolling horizontally (#172258)
  . fix grey block on left of view (#170679)

- avoid smooth scrolling during early stage of layout if the option has
  the WhenEfficient value

BUG: 166413, 172258, 170679
