[PyKDE] mysterious dcopext bug

[Kovid Goyal]

I figured out that this happens because the method getTorrentNumbers returns a 
QValueList<int>. Does anyone know how I can unmarshall that? dcop_next 
doesn't seem to work.

b = QByteArray()
s = QDataStream (b, IO_WriteOnly)
dcop_add(s, 1, 'int')
ok, rtype, arr =  dcop.call('ktorrent', 'KTorrent', 'getTorrentNumbers(int)', 
b)
s = QDataStream(arr, IO_ReadOnly)
print dcop_next(s, rtype)

gives None. I've verified that there are bytes in arr by read rawbytes from s.

Thanks,

Kovid
