Comment # 12 on bug 905863 from Giacomo Comes

I'm having the same problem with lsinitrd. Here is what I have found so far.

running:
lsinitrd /boot/initrd >/dev/null
gives this error message:

cat: write error: Broken pipe

this happens if:
1) you run the command on a console (ctrl alt F1-F6, tty is /dev/tty<n>) 
   if you run the command in a terminal (xterm, konsole, etc, where tty is
/dev/pts/<n>) then there is no error message

AND

2) gnome-keyring-pam is installed. If gnome-keyring-pam is not installed then
again there is no error message.
