after trying this again, i discovered that this fails too.  the only
thing that worked for me was doing it the "manual" way:

    pdf = PropertyValue()
    pdf.Name = 'FilterName'
    pdf.Value = 'writer_pdf_Export'

furthermore, if you need to specify multiple properties, then
virtually duplicating these three lines up and down your code starts
to get old:

    hdn = PropertyValue()
    hdn.Name = 'Hidden'
    hdn.Value = True

    pdf = PropertyValue()
    pdf.Name = 'FilterName'
    pdf.Value = 'writer_pdf_Export'

    ow = PropertyValue()
    ow.Name = 'Overwrite'
    ow.Value = True

you can slightly improve on this with something like:

    props = [PropertyValue() for i in range(nprops)]
    props[0].Name = 'FilterName'
    props[0].Value = 'writer_pdf_Export'
    props[1].Name = 'Overwrite'
    props[1].Value = True
    props[2].Name = 'Hidden'
    props[2].Value = True

instead, i put this all into a function, and it helped clean things up a bit:

def makePropVal(x, y=True):
    pv = PropertyValue()
    pv.Name = x
    pv.Value = y
    return pv

hdn = makePropVal('Hidden')
pdf = makePropVal('FilterName', FTYPES[ftype])
ow = makePropVal('Overwrite')

correction (should be dir path as 1st arg):

unohelper.systemPathToFileUrl('C:/alleclipse/OpenOffice'),
             unohelper.systemPathToFileUrl('test2.pdf')), (PDF,))
