I thought -Suf cannot hurt anything, so I just did -Suf.

I still can't believe you did that! I always say the guideline is to only use -f for one package at a time.

Yes, I always say that, too (on #archlinux.hu irc channel). At least now I can show a concrete example (link to this thread), why it is not recommended to do that. ;-) But the point is that if pacman _were_ bug-free, my -Suf would not break anything!

BTW, -Sud is also bad! :)

Yes. In fact, this was the main reason for -f. I have to choose between breaking some deps* (when your system is really outdated, I am pretty sure, that you will break some ("inverse") deps with -Sf, I did it many times ;-) and force. Clearly, I made a bad decision (I forgot about the upgrade046.py bug).
