Comments copied

I was writing a bug report, but it is already reported and presumably solved, 
the problem that I have. 

When I use Ctrl space to copy msgid to msgstr, the comment comes along e.g. in 
kgeography.po where I get say 

_: africa.kgm\n
Benin

It must be special to me since other people don't seem to get this, but I 
can't figure out what my problem is. I hope someone can help
