This problem appears to be fixable by closing chromium and renaming ~/.config/chromium/ so a new set of config files is created by chromium when it is opened again.
Then cp ~/.config/chromium_old/Default/Bookmarks ~/.config/chromium/Default/
This update introduced the new settings interface so perhaps something to do with that.
