man - broken pipe

I think that is by design and not a bug.  When you are viewing the
manpage, a pipeline of commands has been setup to decompress and format
the manpage.  Because 'less' doesn't ask for more input until you page
down, it means that those commands are all blocked waiting to consume
their input and produce more output.  If you quit 'less' before reaching
the end, the pipeline is broken and the commands all receive SIGPIPE. 
It's normal and harmless.  If you don't want to see the message you can
hit 'end' or '>' before quitting less.  It doesn't happen with small
manpages because they probably fit entirely in a single buffer.
