Follow-up Comment #3:

yes, the find command issued is the problem, because it traverses
both directory 'a' and 'b' ... but in undefined order.
Hence, if it traverses 'a' first, and moves all files to 'b',
and then traverses 'b' and calls the mv(1) command with the
target directory 'b' again, it's clear that this is the same
file.

You may try to reproduce with '... -ls -exec ...' to see what
files get moved, or '-D search'.

To fix it, just traverse directory 'a'.

Hence this is not a bug in find, but rather a misunderstanding
in the use of it.
