I was not able to reproduce this in provided way too. But I noticed that with vim it happens all the time using below commands:

$ vim test.file
:Vexp
Enter any directory

Chip,
I tried to follow netrw-debug but somehow it just saved window output only which is no much of a use. I'm attaching some debug from vim.

I run vim with
vim -u netrw.vimrc --noplugins -i NONE

netrw.vimrc attached too.
