Comment 44 for bug 506798

Something interesting to read (about the same issue and how to reduce impact):
http://www.unixtutorial.org/2009/02/troubleshooting-du-fts_read-no-such-file-or-directory-error/

From what I have quickly checked, if find's fts_read() returns NULL, it just closes FTS structure and goes to next argument. If du's fts_read() returns NULL, it checks for errno - and spits corresponding diagnostics. Difference is in checking function - find has a bit more complex checking function consider_visiting() - maybe some parts from it should be used/adapted in du's process_file() function.
