Error loading saved it file

I saved some recordings using -r but am unable to load them for later analysis:

Showing the package is installed, I'm running Debian 8.2 on this desktop, and Mint 15.2 on the laptop for collecting data in the field. (same errors)
$ sudo dpkg -l libitpp8 libitpp-dev

1. What correction factor is not unreasonable?

1. With CellSearch-1.0 from Evrytania I got a Segfault at this point, so this error message is probably more useful than the backtrace I got with gdb.
   Any ideas how to proceed or debug this?
   Thank you
