Turn off debugging messages

The debugging messages from Fingerprint GUI not only appear in my log files, but when using sudo or su within a terminal, they also appear on the terminal error output. Is there any way I can turn the debugging messages off?

(yes, I can pipe them to null, but that can give other problems)

There is nothing like that in Ubuntu. What is your system? Maybe you need to setup your syslog configuration.

I am on Linux Mint 18, though this also happened in Linux Mint 17.x. It is the only place I see this issue with logging debug info to the terminal.

This is the output on my terminal, when using su, for example:

This is not the debug output of fingerprint-gui! It looks more like debug output from libfprint. But it's not initialized from fingerprint-gui.
