Hello Ludovic,

I have corrected the patch and it works within the VM, in the future I will perform this test.

Now I have a couple of doubts:

a) When I run './pre-inst-env guix environment --ad-hoc nautilus -- gdb --args nautilus' I see:

"/home/jin/guix/nautilus": not in executable format: File truncated
(gdb) r
Starting program:  
No executable file specified.
Use the "file" or "exec-file" command.

Why can not find the executable?

b) What utility is required to use the code comments?
