Rails - Apr 2007 - Possible bug in ActiveRecord::Base#to_xml and caching

So I''ve got this weird problem showing up in the production environment
to
where when I grab xml from resources, the xml results get cached, but not
used. This means that every subsequent request appends the results to the
cache.

This happens when config.cache_class = true; happens in both WEBrick and my
Apache2 fastcgi deploy.

And an example run:

C:\Development\AdminPortal\proto>wget
http://localhost:3000/phone_carriers.xml
...
09:21:34 (869.14 KB/s) - `phone_carriers.xml'' saved [890/890]


C:\Development\AdminPortal\proto>wget
http://localhost:3000/phone_carriers.xml
...
09:21:35 (1.70 MB/s) - `phone_carriers.xml.1'' saved [1780/1780]


C:\Development\AdminPortal\proto>wget
http://localhost:3000/phone_carriers.xml
...
09:21:36 (2.55 MB/s) - `phone_carriers.xml.2'' saved [2670/2670]


As you can see, the exact same request returns increasingly larger results.
There are only 5 records being returned here, but the 2nd request gives me
the results twice, and the third request gives me the results a third time:

<?xml version="1.0" encoding="UTF-8"?>
<phone-carriers>
...
</phone-carriers>
<?xml version="1.0" encoding="UTF-8"?>
<phone-carriers>
...
</phone-carriers>
<?xml version="1.0" encoding="UTF-8"?>
<phone-carriers>
 ...
</phone-carriers>

I''m currently looking into the problem, but was wondering if anyone
here had
run into this or has an idea on where to look. I can''t find anything
via
Google or on the Trac.

My environment:

Ruby version                 1.8.6 (i386-mswin32)
RubyGems version             0.9.2

Action Mailer version        1.2.5

Application root             C:/Development/AdminPortal
Environment                  development

Thanks.
