Comment(by manuq):

 Great finding erikos,

 so as git history says, threads are there to fix this old bug:
 http://dev.laptop.org/ticket/5639

 Which says:

 {{{
 Browse will crash if two things are done in order:

     1) the window is scrolled down at least once, and
     2) the zoom-in button is pressed in View
 }}}

 But I removed threads and I can't reproduce the bug.  Tested in the XO and
 in my dev machine with sugar-jhbuild.  Tried scrolling with the mouse,
 dragging the scrollbar, having the hand key pressed, and with the game
 pad.  Nothing breaks.

 So, this patch would fix it.
