openjdk-6-jre-headless install bug ?

["tv.debian@googlemail.com" <tv.debian@googlemail.com>]

Hi everybody,

I just noticed a strange thing in aptitude logs while updating 
openjdk-6-* in Lenny amd64 :

"Paramétrage de openjdk-6-jre-lib (6b11-9) ...
Paramétrage de openjdk-6-jre-headless (6b11-9) ...
update-binfmts: warning: current package is openjdk-6, but binary format
already installed by sun-java6
Paramétrage de openjdk-6-jre (6b11-9) ..."

The thing is I don't have any Sun related package installed.

This look partially familiar with 
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=Bug%23490672 bug 
#490672 which is now  closed and supposed to be fixed.

Before I reopen a bug I wanted to know if :

I am the only one experiencing it ? Is there any easy workaround I 
missed through my Googling ?

Thanks

Tom
