Ok, I nearly managed to restore all packages, however the following
packages cause the segfault:

gstreamer0.10-pulse
lib32-pulseaudio
libquicktime
pavucontrol
pavumeter
pulseaudio
ttf-liberation

Interestingly the installation via pacman -fU URL succeeds and with
pacman -fS PACKAGE fails.

Is there some debugging version of pacman? For use with gdb to track
down the problem. Or do I have to compile it from source and if so, what
flags do I have to set?

Thanks
