Oh dear that's not good

I wondered if this was due to some of the recent changes adding --skip 
to cherry-pick and revert but I can't see anything obvious at the 
moment. To get that error the sequencer has loaded a todo file (in 
read_populate_todo()) which starts with a revert command. Is it possible 
you were reverting a sequence of commits before you ran the cherry-pick? 
(a single pick or revert does not create a todo list). It could be that 
there was an old todo list left over from a while ago - historically the 
sequencer hasn't been all that good at cleaning up after itself if the 
user committed the final pick or revert with 'git commit' and forgot to 
run 'cherry-pick/revert --continue' afterwards.
