Exception when upgrading via trac-admin

[haf@…]

Installed the plugin on trac 11.5 with Py 2.6. When running trac-admin upgrade, I get the following exception:

Traceback (most recent call last):

I just comment the line 644 in plugin.py and run trac-admin upgrade again. It works for me now. I used Trac 0.12dev.

This should be fixed now for good. It might have been already fixed by the changes made for #6238.
