A bit more here....

So it is segfaulting dereferencing 'tree' in line 526.
(gdb) print tree
$1 = (EIntervalTree *) 0x0
(gdb)

(gdb) up
#1  0x00007ff342deae7a in e_cal_backend_file_start_query (backend=0x16088e0,

1895	
(gdb) print priv
$2 = (ECalBackendFilePrivate *) 0x162ec90
(gdb) print priv->interval_tree
$3 = (EIntervalTree *) 0x0
(gdb) 

and

(gdb) print *priv
$5 = {path = 0x0, file_name = 0x162ed60 "calendar.ics", read_only = 0, 
  is_dirty = 0, dirty_idle_id = 0, idle_save_rmutex = {mutex = {
      runtime_mutex = 0x0, static_mutex = {
        pad = "\001\000\000\000\000\000\000\000\354\016\000\000\001", '\000' <repeats 26 times>, dummy_double = 4.9406564584124654e-324, dummy_pointer = 0x1, 
        dummy_long = 1}}, depth = 1, owner = {
      data = "\200\371\233O\363\177\000", 
      dummy_double = 6.950663201802143e-310, dummy_pointer = 0x7ff34f9bf980, 
      dummy_long = 140682989402496}}, icalcomp = 0x0, comp_uid_hash = 0x0, 
  interval_tree = 0x0, comp = 0x0, default_zone = 0x16455e0, 
  custom_file = 0x0, refresh_lock = 0x162ed80, refresh_thread_stop = 0, 
  refresh_cond = 0x0, refresh_gone_cond = 0x0, refresh_skip = 0, 
  refresh_monitor = 0x0, refresh_timeout_id = 0}
(gdb) 

So, priv->interval_tree is NULL.....
