Registry key already exists

[konstantinkv]

Hello there,
I was having an issue with the <class>proxiblue_newrelic/predispatch_observer</class> call in the config.xml file (line: 95). It was throwing a duplicate key error for some reason:

a:5:{i:0;s:75:"Mage registry key "_singleton/newrelic/predispatch_observer" already exists";i:1;s:1334:"#0 /vagrant/httpdocs/app/Mage.php(223): Mage::throwException('Mage registry k...')
#1 /vagrant/httpdocs/app/Mage.php(477): Mage::register('_singleton/newr...', false)
#2 /vagrant/httpdocs/app/code/core/Mage/Core/Model/App.php(1316): Mage::getSingleton('newrelic/predis...')

I made a fix by providing the full class to it <class>ProxiBlue_NewRelic_Model_Predispatch_Observer</class>, I hear that will be the standard in mage 2.0 anyways. Double checked with xDebug, observer method was firing in v1.9.1.
Cheers,
