If I change your %t to %j, Analog parses the line - it appears that "-" 
isn't a valid %t.

(Tab delimited log files are almost impossible to debug - you have to 
change the tabs to spaces in a sample line, and the \t to %w in the 
LOGFORMAT to have any chance of figuring out what Analog doesn't like).
