I was able to reproduce this with PHP 5.2.9 from the commandline.
php -v
PHP 5.2.9 (cli) (built: May 1 2009 13:47:24)
$> php -r '$d = new DateTime("2009-01-01 00:00:00+0400");
$d->setTimezone($d->getTimezone());'

Description:
------------
If you set a time zone for a DateTime via DateTime::setTimeZone() and
that time zone has no ID you get an error message and the time zone will
not be set.
This can lead to problems if you have two DateTime objects from a source
you do not control and want to format the second DateTime object in the
same time zone as the first.
Reproduce code:
---------------
$d1 = new DateTime('2008-01-01 12:00:00 +02:00');
$d2 = new DateTime('2008-01-01 12:00:00 UTC');
echo $d1->format(DATE_ISO8601), PHP_EOL;
echo $d2->format(DATE_ISO8601), PHP_EOL;
$d2->setTimeZone($d1->getTimeZone());
echo $d1->format(DATE_ISO8601), PHP_EOL;
echo $d2->format(DATE_ISO8601), PHP_EOL;
Expected result:
----------------
2008-01-01T12:00:00+0200
2008-01-01T12:00:00+0000
2008-01-01T12:00:00+0200
2008-01-01T14:00:00+0200
Actual result:
--------------
2008-01-01T12:00:00+0200
2008-01-01T12:00:00+0000
