fxg importer makes extra lines?

Hi,

Im useing TLF build 502 (715519)

I am trying to load a fxg formated text with 3 lines:

<Graphic>

<ns1:TextGraphic xmlns:ns1="http://ns.adobe.com/fxg/2008" whiteSpaceCollapse="preserve">
<ns1:content>
<ns1:p textIndent="0" textAlign="left" marginTop="0" marginRight="0" marginLeft="0" marginBottom="10">
<ns1:span lineThrough="false" fontWeight="normal" fontSize="12" fontFamily="Calibri" color="0x000000">This is first line</ns1:span>
</ns1:p><ns1:p textIndent="0" textAlign="left" marginTop="0" marginRight="0" marginLeft="0" marginBottom="10">
<ns1:span lineThrough="false" fontWeight="normal" fontSize="12" fontFamily="Calibri" color="0x000000">This is second line</ns1:span>
</ns1:p><ns1:p textIndent="0" textAlign="left" marginTop="0" marginRight="0" marginLeft="0" marginBottom="10">
<ns1:span lineThrough="false" fontWeight="normal" fontSize="12" fontFamily="Calibri" color="0x000000">This is third line</ns1:span>
</ns1:p></ns1:content></ns1:TextGraphic></Graphic>

With the demo that on labs i get it right:

This is first line

This is second line

This is third line

but somehow in the last framework i get:

This is first line

This is second line

This is third line

(with extra line betwin the sentences).

Do you have an idea why?

Thanks.
