I can give you some more details on the problem itself. tramp uses
start-process to execute a shell and wait for the initial prompt. But
the shell doesn't output one, since stdin is not connected to a tty (It
should be). I used the following short program:

,----[ isatty.c ]
| #include <stdio.h>
| #include <unistd.h>
| 
| int main(int argc, char **argv)
| {
|     fprintf(stdout, isatty(1) ? "yes\n" : "no\n");
|     return 0;
| }
`----

Running the following command

,----
| [py27] [git:master+] ~/vendor/emacs/ % src/emacs -Q --execute '(progn (start-process "test" "test" "/home/ralf/isatty")(switch-to-buffer "test"))'
| 
| (process:18919): GLib-WARNING **: In call to g_spawn_sync(), exit status of a child process was requested but SIGCHLD action was set to SIG_IGN and ECHILD was received by waitpid(), so exit status can't be returned. This is a bug in the program calling g_spawn_sync(); either don't request the exit status, or don't set the SIGCHLD action.
| Warning: Cannot convert string "Inconsolata-11" to type FontStruct
`----

gives me a buffer with the string "no". The above warning message looks
like another problem.

I worked around the issue by configuring with 
,----
| ./configure --with-x-toolkit=athena --with-xft --without-gconf --without-rsvg
`----

Cheers,
