After some updates I get broken pipe messages when pressing 'q' to exit 
from less. The man pages are printed correctly.

Some examples:
$ man g++
sh: line 1:  1660 Broken pipe             /usr/bin/gunzip -c 
'/usr/share/man/man
1/g++.1.gz'

$ echo a|man bash
sh: line 1:  3456 Broken pipe             /usr/bin/gunzip -c 
'/usr/share/man/man
1/bash.1.gz'

$ echo a|man rsync
sh: line 1:  2748 Broken pipe             /usr/bin/gunzip -c 
'/usr/share/man/man
1/rsync.1.gz'

But:

$ man bash

$ man bc

$ echo a|bc


The pattern is that small man pages never break, medium and big break with 
echo a| in front (the smallest that failed this way is rsync.1.gz, 22kB) , 
huge break without any help (nothing smaller than gcc.1.gz or g++.1.gz 
didn't fail without echo a|).

Any ideas?
