In my case it seems that octet-stream is assigned for documents I open in different openoffices. I have a dual boot dapper/breezy and this issue happens in both each time I open a document in dapper and change it, recently-used entry becomes incorrect in breezy and vice versa. Is it changing the documents that causes this problem? -- OpenOffice writes a .recently-used entry with type "application/octet-stream" when not loading correctly https://launchpad.net/bugs/47506 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
