Hi Zviak,

This is normal. The state system in LTTV only handles kernel traces for 
now. When displaying UST traces, the control flow and resource views 
will be empty.

There are plans on the mid/long-term roadmap to come up with a generic 
way to define "state changes" for UST tracepoints. This will ultimately 
allow any application instrumented with UST to display its own resources 
and control flow.
