Description:
When I run vim, I get this on the commandline:

Traceback (most recent call last):
File "/usr/lib/python2.7/site.py", line 62, in <module>
import os
File "/usr/lib/python2.7/os.py", line 398, in <module>

File "/usr/lib/python2.7/UserDict.py", line 83, in <module>
import _abcoll
File "/usr/lib/python2.7/_abcoll.py", line 11, in <module>
from abc import ABCMeta, abstractmethod

from _weakrefset import WeakSet
File "/usr/lib/python2.7/_weakrefset.py", line 5, in <module>
from _weakref import ref
ImportError: No module named _weakref

After replacing gvim with vim-gtk from AUR, this is no longer an issue.

Before replacing gvim, there are no files named something with weakref in /usr/lib/python2.7 (but there are some in /usr/lib/python2.5).
After replacing gvim with vim-gtk, there are files named something with weakref in /usr/lib/python2.7.

Additional info:
* package version(s)
gvim 7.3.69-2


Steps to reproduce:
Just start vim from the commandline

All installed packages on my system that shows up when searching for vim:
extra/vim-colorsamplerpack 8.03-2
extra/vim-runtime 7.3.69-1
community/clewn 1.15-1
aur/tudu 0.7-1
aur/vim-darkspectrum
aur/vim-debugger
aur/vim-gtk
aur/vim-nerdtree
aur/vim-pydiction
aur/vimpdb

This is after replacing gvim with vim-gtk, the status of all the other packages on the list is the same.
