spurious log file in $XDG_CONFIG_HOME

[hydrargyrum]

According to spec

$XDG_CONFIG_HOME defines the base directory relative to which user-specific configuration files should be stored

So this file should not be there: ~/.config/meteo-qt/meteo-qt.log

This is more suitable:

The $XDG_STATE_HOME contains state data that should persist between (application) restarts, but that is not important or portable enough to the user that it should be stored in $XDG_DATA_HOME. It may contain:

• actions history (logs, history, recently used files, …)

Thanks for underline this, it has been discussed again in the past here: #49 and i didn't change anything.
Maybe i didn"t understand correctly, i will check again

I don't have the $XDG_STATE_HOME in my env variables though in my system (mageia 9, lxqt)

on many systems, XDG_* variables are not set, but per spec, apps should interpret default values in these cases: ~/.local/state/ for XDG_STATE_HOME. If XDG_CONFIG_HOME is not set, it should default to ~/.config.
XDG_STATE_HOME is more recent and less used than XDG_DATA_HOME
