V option is not working

[Meduza]

Hi guys! I`ve started use phpsh and i`ve got error when use v option,
for instance:

include 'test.php' //inside definition of function "nothing"
v nothing

And here is error:

Traceback (most recent call last):
File "/usr/local/bin/phpsh", line 127, in <module>
t_c_ret = s.try_command(line)
File "/usr/local/lib/python2.6/dist-packages/phpsh/__init__.py",
line 918, in try_command
self.editor_tag(line[2:], "vim", read_only=True)
File "/usr/local/lib/python2.6/dist-packages/phpsh/__init__.py",
line 983, in editor_tag
if not self.ctags.py_tags.has_key(tag):
AttributeError: 'NoneType' object has no attribute 'py_tags'

I use debian 6, php 5.3, python 2.6, phpsh latest version. How can i
solve this ?
