 In IPython 0.8.1, typing

   cd x

 produced the very reasonable error message
 {{{
   [Errno 2] No such file or directory: 'x'
   /private/Network/Servers/verger.local/Volumes/User
 data/ClusterUsers/hinsen/projects/crystal_fluctuations
 }}}

 In 0.8.2.svn.r2665, it prints a full traceback that is more irritating
 than useful:

 {{{
   [Errno 2] No such file or directory: 'x'
 ---------------------------------------------------------------------------
   IndexError                                Traceback (most recent call
