Error: "global name 'env' is not defined"

[kup@…]

I have installed NeverNotifyUpdaterPlugin for Trac 0.12.

Now, when changing a ticket, I get the following error displayed in a yellow box on the top of the ticket page:

"The change has been saved, but an error occurred while sending notifications: global name 'env' is not defined"

What did I do wrong?

I'm using Trac 0.12.2 with Python 2.7.3, both from the Ubuntu Precise package sources. The plugin was installed doing

easy_install https://trac-hacks.org/svn/nevernotifyupdaterplugin/0.12/

13433 There was a bug in a recent commit (where a self) was elided. It should be fixed now.

Sorry for the inconvenience

Thanks! Works, like people say, "like a charm" now.
