Also: (gdb) p s
$1 = (struct mansession *) 0x8439be8
(gdb) p s->last_ev
$2 = (struct eventqent *) 0x0
(gdb) p *s
$3 = {ms_t = 0, __lock = {__data = {__lock = 1, __count = 1, __owner = 27117, __kind = 1, __nusers = 1, {__spins = 0, __list = {__next = 0x0}}},
   __size = "\001\000\000\000\001\000\000\000?i\000\000\001\000\000\000\001\000\000\000\000\000\000", __align = 1}, sin = {sin_family = 2,
   sin_port = 21469, sin_addr = {s_addr = 16777343}, sin_zero = "\000\000\000\000\000\000\000"}, f = 0x8390b08, fd = 150, inuse = 0, needdestroy = 0,
 waiting_thread = 4294967295, managerid = 0, sessionstart = 1199522157, sessiontimeout = 0, username = "ma", '\0' <repeats 77 times>,
 challenge = "\000\000\000\000\000\000\000\000\000", authenticated = 1, readperm = 127, writeperm = 127,
 inbuf = "\r\nmmand: meetme list 2\r\n\r\nmeetme list 2\r\n\r\n\000\n meetme list 2\r\n\r\ntme list 2\r\n\r\netme list 2\r\n\r\n", '\0' <repeats 932 times>, inlen = 0, send_events = -1, last_ev = 0x0, writetimeout = 100, list = {next = 0x84a29e0}}
(gdb)

So i wonder if we could simply add
an if (s->last_ev != NULL)  before calling NEW_EVENT
?
