I ran WBPP on this dataset with build 1633 and experienced far fewer of the PCL exceptions, but there were still 3. The frame that failed to calibrate in Juan's test was corrupted by Automatic Cosmetic Correction. It calibrated just fine here with ACC turned off. No question, tracking failed on that subframe, yet registration succeeded.
