I am now able to reproduce at each time like this with helm:

1) Ensure you have no entries for sudo in .authinfo.gpg file.
2) M-x helm-find-files RET // sudo::
3) You are prompted for password
4) At this first shot it should work as expected.
5) C-g to quit, and M-x tramp-cleanup-all-connections.
6) Restart helm-find-files and enter /sudo:: emacs should freeze and
crash.
