Stracing a setuid program changes its behaviour; in this case, sudo doesn't run with effective uid 0, so it exits with an error message very early in execution. You might as well delete the strace log, anyone else can get an identical one with "strace sudo ls" (for example).
How can someone else reproduce what you've seen here? Please set the status back to 'New' once you've replied.
