Public bug reported:

While trying to identify rogue processes that periodically write log
data unnecessarily I identified that zeitgeist is appending DEBUG
messages to the /home/$user/.cache/zzeitgeist/daemon.log  (see attached
log).

Logging messages to a debug log is useful, however on production release
code I don't expect to see DEBUG messages being written to log files:

1.  If they are for debugging only then they should be inhibited in production 
quality code.
2.  Unnecessary debug messages to logs cause additional unwanted writes to the 
disk - when on battery power this can cause laptops to spin drives up and waste 
power.  

Since we are trying to reduce the power consumption I am requesting that
debug messages are not written to this log unless debug is explicitly
turned on.

How to reproduce:

On an installed system observe the daemon.log get DEBUG messages
appended to it over time.  Occurs on idle and non-idle systems.
