net-misc/smb4k-0.6.3 is a candidate for stable, please give it a try.
Stable on amd64.
Stable on x86. But: DESCRIPTION="Smb4K is a SMB share browser for KDE 3.2.x." is not so true :) I have 3.4.3 and it works just fine. And the Polish translation isn't complete, but that doesn't make it unstable anyhow.
x86 done
Marked ppc stable.
