[OpenSIPS-Users] bogus to header in rls subscribe

[Juha Heinanen]

i created s resource list jh-buddies at test.fi, which contains two uris:
test at test.fi and test-buddies at test.fi.

then i tried to subscribe it, but opensips complained about parsing of
to header.

syslog shows that rls_handle_subscribe is called on jh-buddies at test.fi:

May 29 18:45:49 localhost /usr/sbin/pres-serv[20758]: INFO: Handling RLS
SUBSCRIBE <sip:jh-buddies at test.fi>

rls_handle_susbcribes finds the two uris on the list:

May 29 18:45:49 localhost /usr/sbin/pres-serv[20758]:
INFO:rls:resource_subscriptions: Subscription from sip:jh at test.fi for
resource list uri sip:jh-buddies at test.fi expanded to 2 contacts

then rls sends subscribe to test at test.fi and it works fine.

May 29 18:45:49 localhost /usr/sbin/pres-serv[20759]: INFO: Handling
SUBSCRIBE <sip:test at test.fi>

but when it tries to subscribe to test-buddies at test.fi, opensips
complains about parsing of to header:

May 29 18:45:49 localhost /usr/sbin/pres-serv[20758]: ERROR:core:parse_to: unexpected end of header in state 3

create new transaction for SUBSCRIBE <sip:test-buddies at test.fi>

when i check with wireshark how the subscribe looks like, indeed its to
header is broken:

User Datagram Protocol, Src Port: qcp (5082), Dst Port: qcp (5082)
Session Initiation Protocol
    Request-Line: SUBSCRIBE sip:test-buddies at test.fi SIP/2.0
    Message Header
        Via: SIP/2.0/UDP 127.0.0.1:5082;branch=z9hG4bK921.4397b566.0

        From: <sip:jh at test.fi>;tag=374ba85b6c1b7e45caf839d18042c8ae-ef12

        Event: presence
        Contact: <sip:rls at 127.0.0.1:5082>
        Expires: 610

is this a bug?  i think to uri should be the same as request-uri, which
looks ok.

this is with latest opensips 1.6.
