Seems that the exec statement add a __builtins__ key to the locs
dictionnary and IPython don't like it.
Adding locs.pop('__builtins__') before shell initialization fix the problem:
In pylons/command.py at line ~=512:
shell.set_banner(shell.IP.BANNER + '\n\n' + banner)
if '__builtins__' in locs:
del locs['__builtins__']
try:
shell(local_ns=locs, global_ns={})
finally:
paste.registry.restorer.restoration_end()
This don't break the command with IPython 0.9
