[Halld-offline] No photons from hdparsim

[Will Levine]

Hi all,
I just upgraded my Hall-D software to the latest version and now in
some cases, I do not get any DPhotons from hdparsim. Things work as
expected when I run hdparsim on an hddm file generated by bggen, but
not with an hddm file from genr8, which had worked previously. I know
that Blake posted about a similar-sounding problem earlier, but after
reading through that thread I'm not sure if this is the same issue.
