bug#36611: Disappearing profile?

[racin@free.fr]

Hello Ludovic,

.guix-profile points to /var/guix/profiles/per-user/matthieu/guix-profile as it should. But the packages
that I had installed, like file or the urxvt command from rxvt-unicode, are no longer in my path. 
The last time this happened, my manifest file was still working, but guix package -I told that I had no installed package.

It exists, but is entirely empty (has size 0)

Yes, I believe I did. I did not know this would cause such a mess!

Thanks,
