Console Errors Confounding Me

I try to maintain my Blender installation free of console errors. But with all the svns, addons, and key configuration changes, I get a lot of console errors. I can usually fix them by disabling an addon or editing my key file. But I now have some errors that I can not track down.

It is these:search for unknown operator ‘MESH_OT_loopcut_slide’, ‘MESH_OT_loopcut_slide’
search for unknown operator ‘MESH_OT_rip_move’, ‘MESH_OT_rip_move’
search for unknown operator ‘MESH_OT_rip_move_fill’, ‘MESH_OT_rip_move_fill’
search for unknown operator ‘MESH_OT_rip_edge_move’, ‘MESH_OT_rip_edge_move’
search for unknown operator ‘MESH_OT_duplicate_move’, ‘MESH_OT_duplicate_move’

Can anyone tell me how to fix this?
