It looks like you're running 1.7.1 and there were some pretty
serious problems with initializing the user profile that are
now fixed.  You might want to try at least 1.7.2 (I think
you'll get 1.7.4 as the default right now).

Also if you want to diagnose this further, trying running
"Process Monitor" from www.sysinternals.com and filter for
the potential failing processes (bash.exe maybe) and look
to see if it's failing on accessing non-existent registry
entries.
