Backtrace stopped: Not enough registers or memory available to unwind further

The #0 line is not fully printed above, so I've checked pdispatch.c for the source. It looks like that:
pa_assert_se(r->time_event = pd->mainloop->time_new(pd->mainloop, &tv, timeout_callback, r));

(gdb) frame 0

379         pa_assert_se(r->time_event = pd->mainloop->time_new(pd->mainloop,
(gdb) print r->time_event
$1 = (pa_time_event *) 0x81048f0
(gdb) print pd->mainloop
$2 = (pa_mainloop_api *) 0x2424548b
(gdb) print pd->mainloop->time_new
Cannot access memory at address 0x2424549f
(gdb) print tv
$3 = {tv_sec = 134542509, tv_usec = -1219425075}
(gdb) print timeout_callback
$4 = {void (pa_mainloop_api *, pa_time_event *, const struct timeval *, void *)} 0xb6b481e0 <timeout_callback>
(gdb) print r
$5 = (struct reply_info *) 0x8258628

So it seems that the pd->mainloop->time_new pointer is lacking.

Is there any other additional info I can provide?
