apacman tries to install -debug package instead of the main package

With both strip and debug turned on in OPTIONS in makepkg.conf, makepkg will create a package named $pkgname-debug which contains the detached debug symbols. This debug package has the main package as a dependency. When I use apacman to install a package from AUR, it builds and then tries to install the -debug package instead the main package, and fails because of unmet dependency.

Interestingly the name after "built (1)" is correct, but the one after "saving package" is the debug. Looking at the code,

  pkgtar=$(ls $1-${epoch}${pkgver}*${PKGEXT} 2>/dev/null | tail -n 1)
  if [[ $pkgtar ]]; then
    [ -d $savedir ] || mkdir -p $savedir 2>/dev/null || runasroot mkdir -p $savedir
    echo -e "${COLOR5}  -> ${COLOR1}Saving package:${ENDCOLOR} ${pkgtar}"
    cp ${pkgtar} $savedir/ 2>/dev/null || runasroot cp ${pkgtar} $savedir/
    echo -e "${COLOR5}  -> ${COLOR1}Installing ${1}${ENDCOLOR}"

It seems that the glob is matching the debug package name, and that could only happen if epoch and pkgver are empty.
