i have a similer code above and it works fine:
code:
<div spry:region="pvprefix" class="SpryHiddenRegion">
<p spry:if="{ds_UnfilteredRowCount} &gt; 0"><?
echo ucfirst($traducoes['_pagina']);?> {ds_PageNumber} <?
echo ucfirst($traducoes['_de']);?> {ds_PageCount} - <? echo
ucfirst($traducoes['_items']);?> {ds_PageFirstItemNumber} -
{ds_PageLastItemNumber} <? echo ucfirst($traducoes['_de']);?>
{ds_UnfilteredRowCount}</p>
<p spry:if="{ds_UnfilteredRowCount} == 0"><? echo
ucfirst($traducoes['_erro_destinos']);?></p>
</div>

I think this is happening when there is no data to page. In
that case your {ds_PageNumber} is not defined so your spry:if
attribute probabaly ends up looking like this:
spry:if="!= '1'"
You can either quote your {ds_PageNumber} which you should
probably do cause your '1' is quoted:
spry:if="'{ds_PageNumber}' != '1'
or only execute that markup if you have rows of data:
<div spry:region="pvprefix"
spry:if="{ds_UnfilteredRowCount} > 0">
</div>
