Magento: Invalid blocktype

Question

I get the exceptions below. Unfortunately, I can't really find a solution on the internet.

Since these exceptions are just appearing, when I activate the OneStepCheckout extension, I think it's a problem with this one.

Everything is working fine in the shop (as far as I tested already) but I think an exception should always be taken care of.

I already tried a file search for Mage_Braintree_* but didn't find anything.

Any tips?

EDIT: Thanks to Prakash Thapa. I found a braintree part in app/design/frontend/base/default/layout/lotusbreath/onestepcheckout.xml

<!-- For braintree -->
<lotusbreath_onestepcheckout_index_index>
    <reference name="head">
        <action method="addJs" ifconfig="payment/braintree/active"><file>braintree/braintree-1.3.4.js</file></action>
        <action method="addCss" ifconfig="payment/braintree/active"><stylesheet>braintree/css/braintree.css</stylesheet></action>
    </reference>
    <reference name="before_body_end">
        <block type="braintree_payments/datajs" ifconfig="payment/braintree/active" name="braintree_payments_data_js" template="lotusbreath/onestepcheckout/braintree/data_js.phtml" />
        <block type="braintree_payments/form" ifconfig="payment/braintree/active" name="payment.form.braintree" template="lotusbreath/onestepcheckout/braintree/review_js.phtml">
            <action method="setMethodInfo"></action>
        </block>
    </reference>
</lotusbreath_onestepcheckout_index_index>

Since I'm not using any braintree payment extensions, should I delete this part or how should I handle this?

For now, it seems that just deleting (or comment it out) the part is working well.

This error occur due to invalid blocktype in layout xml like

 <reference name="....">
        <block type=".." />
</reference>

Try to find problem design layout like in app/design/frontend/base/default/layout/EXTENSION_LAYOUT.xml EXTENSION_LAYOUT.xml can be anything like braintree.xml or so on.
