I strongly suspect that the problem goes as follows: - buffer-list returns a list of buffers that are all live (i.e. no bug there). - while processing that list, some of its buffers die. So I think the bug is in `desktop-clear` which should skip buffers that have died between the call to `buffer-list` and the moment we get to process them. Stefan "who hasn't looked at the code"
