[ltt-dev] lttv-gui crash

Hi Team,

We are using LTT for our project performance tuning.   Recently after
capturing the trace, when we tried opening the captured trace through
lttv-gui tool, we got a crash and its pretty much consistent.  I am not able
to continue further with my investigation, can you please guide me
on this, like if we have any patch for this tool function properly.

Also, the prevous version of the toolkit use to show which system call is
taking time but with the latest release i am not able to fine any such
information with the trace..

The following are the version of tools i am using.

1) LinuxTraceToolkitViewer-0.8.72-06122006
2) ltt-control-0.30-09112006

Can any of you please point me to right direction.

Thank  you in advance.
