I tracked down the problem we were seeing with the heprep's when viewing
events with no hits. The real problem seems to be in Wired (more
correctly in the jheprep package), but to work around it I just stopped
registering the eventInstanceTree if there are no real hits.
The code is in subversion (but not released).

PS - Dima in case you feel like tracking down the original error, the
stack dump was:
