I had much the same thing happen, and I found a solution, but I don't
promise it's the correct one:
	Try running it with the "-t" switch:

su - dle -c 'rsync -t -e ssh -aqz www.foo.bar:/usr/websites/foo.bar/www
/home/dle/projects/foo/

This attaches a pseudo-terminal to the command. (I suspect there's
something in the user's .bashrc that uses escape chars is the problem.)

I'm idly curious why you wouldn't run this directly under dle's crontab?
