Hi

I run the lttv-gui ,arm the kernel , Start and finally Stop, when I  
try to open the trace in lttv , it will be closed with following  
massage:

lttctl: Starting trace
Executing (as root) : exec /usr/local/bin/lttctl -D trace
Linux Trace Toolkit Trace Control 0.87-09062010

Controlling trace : trace

lttctl: Pausing trace
lttctl: Destroying trace
** Message: statistics viewer : background computation data ready.
**
ERROR:eventhooks.c:1653:after_process_fork_hook: assertion failed:  
(process_child != NULL)
/usr/local/bin/lttv-gui: line 10:  1570 Aborted                  
$LTTV_CMD.real -m lttvwindow -m guievents -m guifilter -m  
guicontrolflow -m resourceview -m guistatistics -m guitracecontrol $*

Thank you in advance for your help
