pidgin-sipe branch debian-jessie terminates screen share

[joakim-tjernlund]

I typically get between two pidgin's who share screen after a few secs:

(15:23:12) sipe: parsing address out of <sip:Joakim.Tjernlund@infinera.com>;tag=2784337691;epid=f534b96dc346

Our Lync server is far away and might have shaky network connection on and off

I note that on pidging sharing its screen I always get this "sip_sec_verify_signature .." msg just before the disconnect:

If I wait about 1-2 mins after starting pidgin and then share it works much longer. It feels like sec msg handling stomps on the screen share

Pidgin-3.0 has the same problem too.

[joakim-tjernlund]

Finally some headway, it seems https://github.com/tieto/sipe/commit/24781d3c81ec3d7e92fb6d0ce74ed6d52c261171 (purple: don't use reliable nice agent ) is causing this.

make is stable again(for now anyway)

[joakim-tjernlund]

This has been fixed in debian-jessie branch now, closing
