Error in viewing the traces (LTTV 0.8.79)

hi all,

     I have 2.6.20 kernel in Multi threading mode , LTTV 0.8.79 ,
LTTng 0.34 . I have taken the trace by executing " lttctl -n trace -d
-l /mnt/debugfs/ltt -t /home/trace "  . When i run LTTV to view the
traces i get an error


** Message: statistics viewer : background computation data ready.
** Message: statistics viewer : background computation data ready.

** ERROR **: file tracefile.c: line 2081 (ltt_update_event_size):

The contents of the trace file is

drwxr-xr-x  2 root root     4096 Oct 18 13:13 control
-rwxr-xr-x  1 root root 60817408 Oct 18 13:28 cpu_0

drwxr-xr-x  2 root root     4096 Oct 18 13:13 eventdefs

What should i do to view the traces ?
