1.10 host bug report

Hi,

It's about 1.10 host. In few words - it doesn’t work at all :) But I spent ONE day and two Ubuntu disks to try to run it :( See attached logs below.

Thanks for the detailed report! I see, we disabled auto-loading the saliency demo module on startup in 1.10 to speedup startup a bit, but indeed that is a mistake for the host.

I think the culprit is here: https://github.com/jevois/jevois/blob/master/src/jevois/Core/Engine.C try un-commenting line 467. I have to run now but will test it on monday.
