Package: python-virtualenv
Version: 1.11.6-2
Severity: important

Dear Maintainer,

Attempting to create a python2.6 virtualenv using the following command:

  virtualenv -p python2.6 venv

Results in the follow error:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/virtualenv.py", line 2378, in <module>
  File "/usr/lib/python3/dist-packages/virtualenv.py", line 830, in main
  File "/usr/lib/python3/dist-packages/virtualenv.py", line 1016, in
ValueError: zero length field name in format

It seems to be due to the use of '{}' for string substitution which is not
compatible with python2.6.
