State-Changed-Why:  
This is a many repeated bug report, I'll close this one we are aware of 
this problem. I am also aware that OpenBSD resolved this one way or the 
other, someone is looking into that already. Thanks for the report 
though it is appreciated a lot. I also hope that you can understand the 
close for duplicated messages.
