QEMU manpages provoke man(1) "can't break line" warnings

I noticed when I ran 'man qemu' for version 2.8.0 I am getting this back at the terminal;


<standard input>:1674: warning [p 1, 188.5i, div `an-div', 0.2i]: can't break line
<standard input>:1677: warning [p 1, 188.8i, div `an-div', 0.2i]: can't break line
