Yes, that's why you should turn debugging on in netrw.vim, not something
else.  netrw.vim should be in your $HOME/.vim/autoload/netrw.vim directory.

vim netrw.vim
:DechoOn
:wq

Then try gx or whatever; you should get a trace.

The trace is time consuming; FYI: to turn debug tracing off:

vim netrw.vim
:DechoOff
:wq
