C'mon, let's call it the right way, you know that reinstall from scratch is the only proper way, but you are lazy enough to ask developers to waste their precious time helping you to spare time on the backup-reinstall-restore process that awaits you, rather than better investing it on devel or in their own private lives.
This is clearly not a support issue but a "please do it for me because I am lazy" issue.
My advice: backup-reinstall-restore. You will be happier, no glitches, no surprises, no time waste.
P.S.: I also had one last aptosid machine; it has gone with a full siduction reinstall.
