By sheer chance, I found a bug in read_config. I was checking to see what
files an agent was reading, and saw lots of 'directory not present' messages
logged for weird name (some including control characters). A short debugging
session later, I found that if the last directory in the config list does not
exist, the code will continue looking for directories past the end of the
buffer. This patch adds an extra condition to the while check, instead of
relying on a break inside the loop.
