[Pharo-project] Broken "Recover Lost Changes"

Oct. 23, 2009

      I have a 4 day old image that just froze. After restarting, I tried to
recover the code changes since I saved my image yesterday, but the list of
changes in the tool are an unordered list going back to February of this
year. Even old code of mine from that time was in the list. After about an
hour I managed to manually select the changes I've made since yesterday, and
file them out. When I try to file them back in, I get an error from the
debugger, and cannot continue. Anyone know what I can do to recover my
source, or point me in the right direction to recover from this.

This is the stacktrace from the debugger :-
