Error messages in .xsession-errors

[claudiux]

This message appears in ~/.xsession-errors when this applet starts:

(cinnamon:2294): Gjs-WARNING **: 23:11:08.600: Some code called array.toString() on a Uint8Array instance. Previously this would have interpreted the bytes of the array as a string, but that is nonstandard. In the future this will return the bytes as comma-separated digits. For the time being, the old behavior has been preserved, but please fix your code anyway to use TextDecoder.
(Note that array.toString() may have been called implicitly.)

This error seems to come from certain stdout provided by spawn_* functions. Maybe use byte_array_to_string() to avoid this kind of message? See in QUtils.js.
