rpg_svo doesn't grab first and second frame

edit

I'm trying to use rpg_svo, but I'm never seeing the normal "Selected frame" messages. This is the output from the suggested dataset on the wiki:

# ./test_pipeline 
[INFO] SVO initialized

[INFO] Init: Selected second frame, triangulated initial map.

This is what happens when I launch mine (note that I only see the "Init: KLT" messages above):
