vim cannot open a specific file and spits out garbage

Hi All,

I am using vim on mac OS 10.8.5, vim --version returns:

I am trying to use vim to edit a file (~/.Rprofile).

The content of ~/.Rprofile is:

Sys.setenv(PATH="/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/texbin:/opt/local/bin:/opt/local/sbin")

(the file is also attached).

If I type vim .Rprofile I get the following garbage:

".Rprofile" 1L, 107CTraceback (most recent call last):
File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 548, in <module>

known_paths = addusersitepackages(known_paths)
File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 266, in addusersitepackages
user_site = getusersitepackages()
File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 241, in getusersitepackages
user_base = getuserbase() # this will also set USER_BASE
File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 231, in getuserbase
USER_BASE = get_config_var('userbase')
File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/sysconfig.py", line 516, in get_config_var

File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/sre_constants.py", line 18, in <module>
from _sre import MAXREPEAT
ImportError: cannot import name MAXREPEAT

I am stumped to what might go on. I attach Rprofile, my vimrc, the Rprofile.swp generated (which looks odd and shows different things depending on what editor I use to open it). this behaviour seems to happen just with this file, but is 100% replicable.

in case it helps this is my $PATH

echo $PATH
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin:/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/usr/local/julia:/usr/local/MacGPG2/bin:/usr/texbin

Best wishes,

F
