apache2 error.log full of: KSystemTimeZonesPrivate::readConfig readZoneTAB and readConfig

[Matthias Busch]

Kolab 3.4 (upgraded from 3.3) on debian 7.8 x64

my /var/log/apache2/error.log is full with:

unnamed app(29112) KSystemTimeZonesPrivate::readConfig: readConfig(): 
local zone= "UTC"
unnamed app(29112) KSystemTimeZonesPrivate::readZoneTab: readZoneTab( 
"/usr/share/zoneinfo/zone.tab" )

somehow, my second kolab system (almost identical setup except wallace 
not in the postfix chain) does not show those messages.

both are setup with timezone Europe/Berlin, are running ntpd to have 
(and do have) the correct time.

If someone knows how to fix that error I'd be very grateful.

Further information can be made available if I know what you need...

Thanks
Mat
