[SR-Users] Dialog module is crashing after setting track_cseq_updates to 1

Hi,
after setting track_cseq_updates to 1 in module dialog (and calling
dlg_manage() from request_route) I'm getting reproducible crashes in both
stable (4.2.2) and dev (4.3.0-dev3, 2015-01-28) releases.
I made the change to cope with CSeq not being incremented when sending
another INVITE with authentication information with by calling
uac_auth()/append_branch()/t_relay(). The SIP trunk on the asterisk server
I'm forwarding the request to requires so and sends me an "401
Unauthorized" message after the first INVITE.
Anyone using it would help me with the configuration?
Should I post to the dev list?
Thanks for any help,
Fernando Aquilino
