Closed#2: Error on submitting event: null parameter for ksort()

I have created as simple an event as possible to test the email template.

I have a categories section that contains a single text input field: Title.

I created an email template that looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:output method="xml"
    omit-xml-declaration="yes"
    encoding="UTF-8"
    indent="yes" />

<xsl:template match="/">
    <xsl:text>The category was successfully created.</xsl:text>
    <xsl:copy-of select="." />
</xsl:template>
</xsl:stylesheet>

I created an event, Email: Category Created, and attatched it to a page, Email, with the following template:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:output method="xml"
    doctype-public="-//W3C//DTD XHTML 1.0 Strict//EN"
    doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"
    omit-xml-declaration="yes"
    encoding="UTF-8"
    indent="yes" />

<xsl:template match="/">
    <h1><xsl:value-of select="$page-title"/></h1>
    <form method="post" action="" enctype="multipart/form-data">
        <input name="MAX_FILE_SIZE" type="hidden" value="5242880" />
        <label>Title
            <input name="fields[title]" type="text" />
        </label>
        <input name="action[email-category-created]" type="submit" value="Submit" />
    </form>
</xsl:template>

</xsl:stylesheet>

When I enter a value of Email in the Title field and click on the Submit button, the following error is returned:

ksort() expects parameter 1 to be array, null given
