I renamed the profile and restarted Gimp (with it's horrible dark screen!). With a small file I was able to do a "select by colour" and then "save selection to channel".
The file which caused my original problem - an .NEF file of 52 MB which converts to a .TIF of 275 MB and 850 MB when loaded into Gimp - I was able to do a "select by colour" but it refused to "save selection to channel".
I have 32 GB of RAM and my Tile Cache size I have set to 24 GB.
I think I need to try with other images of similar size, although they have not given me problems in the past.
