Details

After the firefox update there are the two package files in pacman cache:
firefox-18.0-2-x86_64.pkg.tar.xz
firefox-18.0.1-1-x86_64.pkg.tar.xz

The command 'paccache -d -k1 -vv' gives:

==> Candidate packages:
/var/cache/pacman/pkg/firefox-18.0.1-1-x86_64.pkg.tar.xz

==> finished dry run: 1 candidates (diskspace saved: 18.33 MiB)

So the script wants to delete the wrong package file, it should be:

/var/cache/pacman/pkg/firefox-18.0-2-x86_64.pkg.tar.xz
This task depends upon

More likely the bug is in pacsort, not paccache.

edit: Or possibly vercmp...

$ vercmp 18.0-2 18.0.1-1
-1

$ vercmp /var/cache/pacman/pkg/firefox-18.0-2-x86_64.pkg.tar.xz /var/cache/pacman/pkg/firefox-18.0.1-1-x86_64.pkg.tar.xz

$ vercmp firefox-18.0-2-x86_64.pkg.tar.xz firefox-18.0.1-1-x86_64.pkg.tar.xz

$ vercmp 18.0-2-x86_64.pkg.tar.xz 18.0.1-1-x86_64.pkg.tar.xz

Fixed this mostly in pacsort:
