Sparse 3D scene reconstructed by SfM10 (number of trials in AC-RANSAC = 1000, max number of iterations in Bundle Adjustment = 1000, min separation angle = 1.5, and max reprojection error = 16).
Hmmm, something went terribly wrong here. Let's hike up the number of trials in AC-RANSAC and see if that's enough to solve the problem.

Looks like it solved the problem nicely.
