No problem, here it is:

I had to restart it to get it into gdb again. I'm showing the requested
info along with the new backtrace.

(gdb) print *data
$1 = {policy = 0x734890, device = 0x750230, id = 0}

(gdb) print *policy
$4 = {manager = 0x731030, update_state_id = 0, pending_activation_checks = 0x0,

  cur_hostname = 0x0, hostname_changed = 0}

(gdb) print specific_object 
$5 = 0x0
