Trying to restore just one directory and I keep getting BotoServerError 500 Internal Server Error! This is very frustrating and shakes my faith in the ability of TKLBAM to properly do backup and restore! What am I doing wrong?

tklbam-restore --skip-database --skip-packages --limits "/var/www-ssl/some/deep/dark/directory/assets/default/javascript" --time 2013-11-26T15:01:48 8

after I enter my passphrase, I get this response (some areas redacted for security with @ symbols):
