OK, I've spent the whole morning digging the bug and I've found it. The function get_all() in /usr/share/perl5/X11/Auth.pm silently returned nothing because my ~/.Xauthority seemed corrupted:
[EMAIL PROTECTED]:~$ xauth
Using authority file /home/cyb/.Xauthority
xauth> list

("wide" is my hostname)
I really have no idea how this corruption happened but I simply
removed the file, restarted X11 and cssh is happily working again.
The corrupted file is 2495 bytes long whereas the valid one is only
115 bytes long, it's quite a difference. I kept a copy if anyone needs
it.
I'm also wondering why all my other X11 apps were working normally
with this corrupted .Xauthority file and why cssh is the only one to
fail.
I would have saved a lot of my time if libx11-protocol-perl was
displaying an explicit error message instead of:
"Can't read: at /usr/share/perl5/X11/Protocol.pm line 2301".
I guess other users might waste a lot of time too because of that so
I'll reassign this bug as "wishlist" to libx11-protocol-perl.
Thanks.
