Thanks Tom for tracking this down. I suspect what is happening is the
setroubleshootd process is not exiting because one of its threads is
still running. In python there is a flag to control if child threads
exit when the main thread does and some behavior I have to investigate
more with respect to threads and signals. We had put some code in to
address some of this but it sure looks like its not working as expected.
Could you tell me what version of setroubleshoot you are running so I
can see if that version had the code changes? I'll also add this issue
to me to-do list for today.

Report above with setroubleshoot-0.45-1. I just installed
setroubleshoot-0.47-1.  I'll rerun and report any changes.
