Tramp hangs when used with ESS

[Guha, Rishab]

Hi,

Tramp has been hanging on 'Sending password' for me whenever I try to use it. This includes the simplest test case of C-x C-f /sudo::/etc/hosts.

After some trial-and-error with my .emacs, it looks like the problem occurs if and only if ESS is active. Unfortunately, I haven't been able to figure out anything more than that. Debug log output from the simplest possible test case, with init.el looking like http://pastebin.com/WVq9TTdA, is here: http://pastebin.com/XJp7abc3

I haven't found any way of replicating this without activating ESS. Note that though the message log says that Tramp is sending a password, I was never prompted to enter a password--the minibuffer proceeded directly to 'Sending password'

This has been driving me crazy for the past couple of days--any help would be really appreciated!

Best,

Rishab
