 To induce the crash, do the following:
  1) Browse to wiki.laptop.org[[br]]
  2) Click on "join us" link in intro statement (goes to
 "Participate")[[br]]
  3) Click on "Get your students involved" link in "Are you a teacher?"
 section (right at the top of the page).  This links to an anchor down the
 page.[[br]]
  4) Press the back button.  Browse crashes.

 I have experiences over a dozen crashes in Browse after pressing the back
 button, very inconsistently.  I am unable to say whether all those crashes
 have been due to backtracking from an anchor link, although it is possible
 (nevertheless, there may be another bug out there).

 The log contains the following

 This was reproduced on two G1G1 build 650 machines.
