Curious message at startup

[terminator356]

Just noticed this odd second line at startup, a quick search says
possibly something to do with Xorg. Makes no sense. Any ideas?:

/home/me/muse-20200607-master/bin> /home/me/muse-20200607-master/bin/muse3 -M -m -D -a
Invalid MIT-MAGIC-COOKIE-1 keyConfig File </home/me/.config/MusE/MusE/MusE-seq.cfg>
LOCALE en_US

After viewing more of them it turns out there's supposed to be a space in the message,
it simply "bleeds into" the next message so the messages should look like this:

Invalid MIT-MAGIC-COOKIE-1 key
Config File </home/me/.config/MusE/MusE/MusE-seq.cfg>
