[syslog-ng]Square Brackets in match()

Syslog-ng: 1.5.18 and 1.4.11 If I have a message that looks like this: Jun 3 00:16:52 X.X.X.X/X.X.X.X rido-ott[System]: request for unserviced tcp:X.X.X.X-25 from X.X.X.X denied if I want to match this part [System]: request for unserviced I have to leave out the leading '['. eg match("[System]: request for unserviced") will not but match("System]: request for unserviced") will Is this a bug in the matching grammar? If I used normal regexp syntax and escape the '[' as in '\[' is stiil won't work. Clayton PS Thanks Balazs for your anwsers to my last question and for syslog-ng
