[SIP Beyond VoIP] sylkserver exception after handling refer

[Juha Heinanen]

i tried (with None audio devices) if conference would work.  when i gave
/add_participant command, sip-session client sent refer to sylkserver.
sylkserver got it and wrote to syslog:

Nov  5 12:10:04 sip sylk-server[16724]: [conference] sip:jh at test.fi added sip:test at test.fi to sip:+35892345671*3655*8681 at cf.test.fi

then sylkserver sent out notify and after that got into trouble:

Nov  5 12:10:04 sip sylk-server[16724]: error: Exception occured in observer <sylk.applications.conference.IncomingReferralHandler object at 0xa9fdbcc> while handling notification 'DNSLookupDidSucceed'

Nov  5 12:10:05 sip sylk-server[16724]: TypeError: __init__() takes exactly 1 argument (2 given)

i have tried to check that i have all the latest packages installed, but
for some reason there is still the above argument mismatch.
