I got two errors in screenfetch
# screenfetch
[[ ! ]] Property "/Gtk/FontName" does not exist on channel "xsettings".
[[ ! ]] /usr/bin/screenfetch: line 817: [: 2582.3: integer expression expected

+normal output

using bash -x I got some more insights:

> xfconf-query -c xsettings -p /Gtk/FontName
Property "/Gtk/FontName" does not exist on channel "xsettings".

it seems, it does not handle fractional MHz values properly
