When the HOME path is just '/' python says that the home path is ""
(zero length string)

I was able to reproduce this issue in 2.5.2 and 2.6 (no idea about 3.0)

Here's an example:

$ HOME=/ python -c 'import os;print os.path.expanduser("~")'

$ HOME=/tmp python -c 'import os;print os.path.expanduser("~")'

$ HOME=a python -c 'import os;print os.path.expanduser("~")'


I just used "if !os.path.isdir(os.path.expanduser('~')):" check in
my application to avoid messing around the resulting paths when the
application runs.

The correct response should be '/' instead of ''.
