Document with missing trend line

Open attached document. The chart should show an exponential trend line.

The document has been created with LibreOffice. It adds some attributes with namespace "loext:" to the <style:chart-properties> element. But the correct attribute chart:regression-type="exponential" is present too. OpenOffice should ignore the foreign attributes and evaluate the valid ones, instead of dropping the whole element.

WIN7 64bit AOO420m1(Build:9800)  -  Rev. 1630928 shows the value Symbols, but the line is missing. format Values dialog for line style shows "none"

Already broken with AOO 3.4.0

Looks ok with OOo 3.3.0 when open, but line disappears after double click on chart or <f9>

http://odf-validator2.rhcloud.com/odf-validator2/ finds some additional ODF errors, I can't tell whether that rating is true and weather those errors might be related:
