Docbook->AsciiDoc empty table entry outputs '[multiblock cell omitted]'

[msgilligan]

I'm using pandoc version 1.12.3.3. The command used is:

pandoc entry-empty.xml -f docbook -t asciidoc --atx-headers --base-header-level=2 -s -o entry-empty.adoc

The input contains:

    <informaltable>
      <tgroup cols="1">
        <tbody>
          <row>
            <entry></entry>
          </row>
          <row>
            <entry/>
          </row>
        </tbody>
      </tgroup>
    </informaltable>

The actual output is:

[cols="",]
|=========================
|[multiblock cell omitted]
|[multiblock cell omitted]
|=========================

The expected output is:

[cols="",]
|=========================
|
