Use of uninitialized value $filename

[targzeta]

Hi, when I run cssh I have these errors:

Use of uninitialized value $filename in hash element at /usr/share/perl5/App/ClusterSSH/Host.pm line 70, <$ssh_config_fh> line 1.
Use of uninitialized value $filename in open at /usr/share/perl5/App/ClusterSSH/Host.pm line 72, <$ssh_config_fh> line 1.

my ~/.ssh/config is:

$> cat ~/.ssh/config 
Include conf.d/*

whit debug 3 I have:

Reading SSH file: /home/targzeta/.ssh/config
Use of uninitialized value $text[1] in print at /usr/share/perl5/App/ClusterSSH/Base.pm line 135, <$ssh_config_fh> line 1.
