With the patch, testdb just prints the error (when loading pkgcache),
but the retval is 0. If _alpm_db_populate() returned with -1, then
testdb would catch the error (and pacman would exit). First I wanted to
choose this strict behaviour (duplicated entries => error, exit), but I
saw that we never do that atm (with broken entries, etc.) and I was a
bit unsure about sync repos (hm, maybe we should print the repo name in
the error message...): Iirc pacman always loaded sync repos' pkgcache
earlier, so a bogus sync repo would have made pacman disfunctional
(including -Sy), and we have different GUIs.
If we prefer the strict behaviour, I will resubmit the patch.
