Research direction
Start by locating the Haskell implementation of the list function and reproduce the Data.ByteString.last: empty ByteString exception with mailbox names of different lengths. Trace which mailbox-name value becomes empty, then add coverage showing that list no longer calls last on an empty ByteString.
