How do you turn off debugging messages?

[Scott Simpson]

I'm getting messages like

(gnucash:9085): gnc.backend.file.sixtp-DEBUG: Finished with end of 
<price:type>
(gnucash:9085): gnc.backend.file.sixtp-DEBUG: Finished with end of

when gnucash starts up. How do I turn this off? My ~/.gnucash/log.conf file 
looks like

[levels]
gnc=message

gnc.bin=warn
gnc.gui=warn
gnc.backend.file=warn
gnc.smc=warn

gnc.engine.sx=warn
gnc.app-util.sx=warn
gnc.backend.file.sx=warn
gnc.gui.sx=warn
gnc.gui.frequency=warn

GLib=error

[output]
to=stderr
