I don't know why.
The --sbox-call means that the name of the binary and every argument, including argv[0], is given in command line. In some cases this can't really be resolved from the actual binary called, so it is being preserved. If I remember correctly, the first argument after --sbox-call (that is the actual binary name) is used to locate the actual binary that is being called, but rest of the arguments are given to the elf (eg. we skipped the program name, but kept the argv[0]; in scratchbox these two can be different in quite many cases). That stuff is noise emitted by fixing #277. See also 20060918133615-2603f-4d93d27bb57984387af2333030cc6f62eacfcda5.gz in 1.0/scratcbox. -Toni
