Why does "enter time machine" crash my computer?

Question

The title is pretty descriptive. The "crash" is that I get the spinning beach ball of death and over the course of a few seconds my machine becomes completely non-responsive to input (keystokes stop working, then the wiggling the mouse stops working). I have do hold down the power button to reset the machine after that. Although I'm quite familiar with http://pondini.org/OSX/Home.html I don't see that anything readily addresses "Time Machine crashes my whole OS". Any ideas? Thanks!

Answer 1

Here a log of what happens. I got this same effective log in two different situations: first when I ran an attempted backup, then again basically the same when I changed the computer name and tried again. That second attempt is probably pretty telling since there is no sparsebundle with the new computer name, meaning the error of "diskimagealreadyattached" cannot be true.
