Hello,

	I have a trace that is causing problems. The gui comes up ok, but when I zoom in, it dies 
with:

** (lttv.real:32675): CRITICAL **: unknown state : (null)
**
** ERROR:(eventhooks.c:273):prepare_s_e_line: assertion failed: (FALSE)

In the gdb I see the following for "process", followed by the stack trace. "process" is 
optimized out in prepare-s_e_line, but I see the its value in draw_closure.

  print *process
$5 = {pid = 3571, tgid = 3571, ppid = 1, creation_time = {tv_sec = 33074, tv_nsec = 
156251541}, insertion_time = {tv_sec = 33074, tv_nsec = 156251541}, name = 3934, brand = 
62, pid_time = 3936, execution_stack = 0x201c620, state = 0x9bdf4d0, cpu = 1, usertrace = 
0x0, user_stack = 0x1f32c20, current_function = 0, type = 78, target_pid = 0, free_events = 0}
(gdb) print *process->state
$6 = {t = 65, n = 70, entry = {tv_sec = 33074, tv_nsec = 191892096}, change = {tv_sec = 
33074, tv_nsec = 191892096}, cum_cpu_time = {tv_sec = 0, tv_nsec = 0}, s = 0}
