Upgrading mplayer worked and from /var/log/dpkg.log:

2012-05-08 12:29:57 upgrade mplayer:amd64 2:1.0~rc4.dfsg1+svn33713-5 2:1.0~rc4.dfsg1+svn34540-1+b1

So somewhere inbetween those versions it was fixed. And I think you ment
"Breaks: mplayer (<< 2:1.0~rc4.dfsg1+svn34540-1+b1)" instead of
replaces.
