I built several versions of the libs : - 4.3.4-3+old : without the hal patch, it should work for you as it's in fact 4.3.4-1. Of course, it doesn't work for me as I'm bitten by the original bug :) - 4.3.4-3+gentoo : with the gentoo patch (quite similar, but to be sure) - 4.3.4-3+trunk : with a full backport of the files from KDE trunk (future 4.4.0 version) I'm uploading them to http://alioth.debian.org/~wdgt-guest/pub/hal ; they are gpg-signed with my key (B63A3AD9).
