T & E plugin always in need of an upgrade even though log says it is fine

[mgara]

I have been trying to install your plugin from svn source. I did the setup and copied the egg file into the plugins/ directory.

After adding the line

timingandestimationplugin.* = enabled

and running a trac-admin upgrade, I still get the error message that

TracError: The Trac Environment needs to be upgraded.

Even though

sudo trac-admin . upgrade
Database is up to date, no upgrade necessary.

And futhermore, in the trac log I have:

2012-07-05 18:27:56,785 Trac[api] DEBUG: T&E BEGIN Reports need an upgrade check
2012-07-05 18:27:56,786 Trac[reportmanager] DEBUG: T&E Checking for custom_report upgrade
2012-07-05 18:27:56,948 Trac[reportmanager] DEBUG: T&E END Checking for custom_report upgrade
2012-07-05 18:27:56,949 Trac[api] DEBUG: T&E END Reports need an upgrade check
2012-07-05 18:27:56,950 Trac[api] DEBUG: T&E NEEDS UP?: sys:False, rep:False, stats:False, fields:False, man:False

which I take to mean that T&E needs an upgrade.

The only way I can stop the error is by disabling this component in the trac.ini.
