Well, those are not the actual last few lines before the crash, because 
I see a return from KERNEL32.UnhandledExceptionFilter() without the 
call. I think the program actually crashed somewhere before the call to 
that function. I often grep through the log for "xception" (without 
"E"/"e" so that case does not matter) to find the first place in the log 
where that word shows up.
