tramp hangs also on Solaris 12

[Jiri Sasek - Solaris Prague]

I am trying to open the external file via Tramp using ssh in:
GNU Emacs 24.3.1 (x86_64-pc-solaris2.12, GTK+ Version 3.4.4)
... on Solaris 12 against Solaris 12 (Solaris 11 should be the same).

Debug level is set to 21 and it seems the last remote command is:

16:13:57.963155 tramp-send-command (6) # ( (test -e 
/export/home/jack/on12-clone/usr/src/lib/gss_mechs/mech_krb5/mech/acquire_cred.c || test -h

16:13:57.964971 tramp-accept-process-output (10) #  (there are repeating ^G)

...but if I perform the command from command prompt (on remote end):

address@hidden:~$ ( (test -e /export/home/jack/on12-clone/usr/src/lib/gss_mechs/mech_krb5/mech/acquire_cred.c 
|| test -h /export/home/jack/on12-clone/usr/src/lib/gss_mechs/mech_krb5/mech/acquire_cred.c) && 
/usr/bin/stat -c '(("%N") %h %ue0 %ge0 %Xe0 %Ye0 %Ze0 %se0 "%A" t %ie0 -1)' 
/export/home/jack/on12-clone/usr/src/lib/gss_mechs/mech_krb5/mech/acquire_cred.c || echo nil) 2>/dev/null; 
echo tramp_exit_status $?

tramp_exit_status 0

...everything looks fine.

Also if I open the file direcly in jurasek-nb:~jack/(i.e. .emacs) I can modify 
the write it back. Problem happens on files in subdirs only.

Please note:
I have also changed values in .emacs.d/tramp (using vi ;-) when emacs is off) because there are 
paths for some utilities which output can vary depending ont he fact if the POSIX utility (in 
/usr/bin/) nor Gnu (in /usr/gnu/bin/) is used  ...i.e. "/usr/gnu/bin/id" gives output 
more like "/usr/bin/id -a"...
I have also changed "/bin/sh" to "/bin/bash" in .emacs.d/tramp

Can anybody push me to fix this issue please?

Many thanks in advance,
Jura
