Translation doesn't work on breadcrumbs added by xml

Question

I'm building a custom page.

I add breadcrumbs like this (and it works well).

<brand_brand_index translate="label">
        <reference name="breadcrumbs">
            <action method="addCrumb">
                <crumbName>Home</crumbName>
                <crumbInfo>
                    <label>Home</label>
                    <title>Home</title>
                    <link>/</link>
                </crumbInfo>
            </action>
            <action method="addCrumb">
                <crumbName>All Brands</crumbName>
                <crumbInfo>
                    <label>All Brands</label>
                    <title>All Brands</title>
                </crumbInfo>
            </action>
        </reference>
        [[...]]
    </brand_brand_index>

The problem is label not translated in front-end. It shows Home / All Brands instead of translated version.

The things I made sure:

1. Added translate="label" to handler
2. Cache cleared (acctually I turned off caching)
3. Translation syntax is correct (I put in Mage_Core.csv)
4. Label is translated properly by php code (eg: $helper->__('All Brands');

Help me to figure it out, please.

Thank you.
