autotest + Growl problem : garbled notification text

Hi all,

I'm trying to setup autotest (gem zentest 3.4.1.) to send notifications
to Growl (see .autotest contents below)

It works fine when all the tests pass, and displays the following
notification :
      1 tests, 0 assertions, 0 failures, 0 errors

BUT when a test fails, the notification looks like this:
      0x226e0dc @new_record=true,
@errors=#<ActiveRecord::Errors:0x226908c @base=#<User:0x226e0dc ...>,
@errors

I tried all the different autotest config code I could find on the web,
but the only one that works is the one below.

Any idea?
TIA

Maybe you should file a bug?

Or email the authors directly?
