Actually no sooner had I said that, but I worked out what is going on (and added the following to bugzilla).

Hold shift and begin pressing left arrow to create a selection and expand it left. Continue until the selection starts from the beginning of the current line. Then press left again, to attempt to start the selection on the end of the previous line. LyX will abort, with an error "attempt to subscript container with out-of-bounds index -1". This is not the only way to generate this error but it is probably the easiest to reproduce.
