Event seeking error in 15.3.0

[sboeser]

Sorry to complain again, but I'm having trouble running HepMCBrowser in 15.3.0 also.. It starts just fine but when I go the first event (or any other event for that matter) nothing happens and I get the below error message in the terminal window. I guess something with the seek mechanism has changed recently..?
