Privacy: calGoogleSessionManager writing to syslog [linux]

[NoOp]

I notice that Mozilla Thunderbird and SeaMonkey calendar
extensions are writing to syslog:

[calGoogleSessionManager] Creating session <snip>
gnome-session[4983]: [calCachedCalendar] Performing playback operation
add on 0 items to <snip>@gmail.com

gnome-session[4983]: [calGoogleSession] Token expired 1478xxxxx seconds
ago, resetting
gnome-session[4983]: [calGoogleCalendar] Logging in session <snip>

The information contains email account information, reminders, id tags
etc that I would prefer not be written to syslog. Is there a way to turn
this off?

What are your settings for the advanced preferences calendar.debug.log
and calendar.debug.log.verbose? Both should be set to false by default
and this case nothing should be logged according to

Thanks! That was the issue - both were set to true.
