Exception after installing Babel

[Sebastian Krysmanski <sebastian@…>]

After installing Babel (using easy_install), running Trac using tracd gives me the following stacktrace (before installing Babel everything worked fine):

Traceback (most recent call last):

This is a duplicate of #9439. As a workaround, you can de-install Trac, and re-install after installing Babel.

The fix we already have in 0.12-stable seems to be incomplete, so I'll need to work on it some more.

You simply need to check whether this directory exists. I've created the directory afterwards and the error disappeared.
