Here's a comparison between the shell command with M-!:

Sat 2012-09-15 16:46:33 +0200
0.182  bazaar version: 2.5.1
0.182  bzr arguments: [u'log', u'-r-1', 
u'/data/steve/bzr/emacs/quickfixes/lisp/gnus/gnus-group.el']
0.186  looking for plugins in /home/steve/.bazaar/plugins
0.196  looking for plugins in /usr/lib64/python2.7/site-packages/bzrlib/plugins

0.417  encoding stdout as osutils.get_user_encoding() 'utf-8'
0.480  return code 0

and `C-u C-x v l RET RET' on the same file:

What is happening between the last two entries that takes 18 seconds?
