Attempting to open an older timeline ("Integrated Timeline (partial)" in the hackathon db) causes a NPE to be thrown and a grey screen to be displayed.
Cursory investigation suggests that the "type" field of the activity is null (as these activities were created before the addition of a "type" field), but this is not checked by ActivityView before drawing. Easiest fix is to modify getType() in the activity component such that it never returns null.
