Just to mention the follow-up: I used kmail and its convert program on the old dbx files, and it worked fine. But the results were in maildir format (each message in a separate file), not in mbox format (a whole lot of messages in one file, which apparently Thunderbird/Icedove are used to). But some googling revealed a maildir-to-mbox shell script: http://tinyurl.com/6zdn4s
This produced mbox files that I could drop into my wife's Thunderbird local mail directory. The only trouble was that the script did not recognise filenames with spaces in them (even when quoted with a reverse slash character). But simple renaming fixed this. Everything works fine now.
