Traceback (most recent call last):

from IPython.CrashHandler import CrashHandler
ImportError: No module named CrashHandler

Can reproduce this by calling python2.7 directly. Seems to be a compatibility break in ipython-0.12; ipython-0.10 ships a matching module. The [official list of backwards-incompatible changes](http://ipython.org/ipython-doc/rel-0.12/whatsnew/version0.12.html#backwards-incompatible-changes) doesn't include this, though.
