Issue of Trac 1.2.2 "about" link

[johnt888@…]

Hi -

Received the following error message when I clicked the upper right "about" link:

Not sure it's related to some plugin or upgrade from an old database, a brand new database is fine. I will check more details and report back if it's required

The error is in retrieving the version from the textile package (a dependency).

I would guess it's due to running an upgrade without shutting down the web server: TracUpgrade#a1.Bringyourserveroff-line.

[Jun Omae]

Reproduced it.

textile.__version__ is available since textile 2.1.6, however python-textile package in Ubuntu 14.04 is 2.1.5.
