When this works like expected, then only because you have only something 
like

<photo>
  <anyelement>
    text
  </anyelement>
</photo>

(matching)

and

<photo>
  <anyelement>
    <anotherelement/>
  </anyelement>
</photo>

(not matching)

It won't match on

<photo>
  <anyelement>
    text
    <anotherelement/>
  </anyelement>
</photo>

(text is != '', but count(*) is 1 (<anotherelement/>))

Maybe it already matches your needs, but I think it's better to use

xsl:template match="photo/*[normalize-space()]"

(strips whitespace characters)
