Also perplexed by this one, there's clearly a checkpoint here:

inthe.am/inthe_am/taskmanager/tasks.py

Line 421 in 331ac59

with git_checkpoint(store, "Processing Trello Action", data=data):

& the mechanism used for checking for that checkpoint just looks for an active lock in redis. So, maybe this was something that happened while redis was being restarted or something?
