Strange behaviour for VCARD ADR items

[ukleinek]

I'm not sure if I do something wrong, vobject is just designed for US addresses(?) or there is really an issue.

>>> import vobject
>>> s = """BEGIN:VCARD
... VERSION:3.0
... FN:John Doe
... N:Doe;John
... ADR;TYPE=home:Beispielstraße 42, 12345 Musterstadt
... END:VCARD
... """
>>> v = vobject.readOne(s)
>>> v.adr
<ADR{'TYPE': ['home']}Beispielstraße 42
 12345 Musterstadt
,  >
>>> str(v.adr.value)
'Beispielstraße 42\n 12345 Musterstadt\n,  '

The address is how an address in Germany looks like. When looking at the last line I wonder where the comma and two spaces at the end of v.adr come from. Would be great to learn if the problem is on my side or this is indeed a problem in vobject. It might also be nice to strip the subcomponents to get rid of the space before 12345
