Once again, missing application/octet-stream has revisited me. Where does TDE store this information, and is there a way to lock that particular entry so that it doesn't disappear now and again? There must be a bug somewhere in TDE's mime handling routines that causes it to delete this entry when one is adding other entries to the table, but I haven't a clue as to which component a bug report should be opened...
