Using tramp-log-to-file variable with -Q

[Mikhail P]

Hi, I am trying to use loggin to a file feature. To do so I cloned and compiled tramp from source. Then I try to run

~/bin/emacs -Q -l tramp --eval="(progn (add-to-list 'load-path \"/path/to/elisp/dir/tramp\") (require 'tramp) (setq tramp-verbose 10) (setq tramp-use-ssh-controlmaster-options nil) (setq tramp-debug-to-file t))" 

Running M-x locate-library gives the correct path to compiled tramp, not the sytem-wide one. However C-h v tramp-debug-to-file does not give anything. I see tramp debug buffers but nothing in /tmp (which is the temporary-files-folder). Everything works if I run it without -Q ... i.e. with evaluating my .emacs file. 

Thanks,

Mikhail
