Hello,

I am also on Arch Linux, but did not get such problems yet. But I often see 
install files of (even official) Arch Linux packages which try to run 
install-info 
more often than needed.

For instance the package for texinfo has the following install file:

infodir=usr/share/info
filelist=(info.info info-stnd.info texinfo.info{,-1,-2,-3})

post_install() {
  # Scan *all* info files on install
  for file in $(find $infodir -type f ! -name dir); do
      install-info $file $infodir/dir 2> /dev/null
  done
}

post_upgrade() {
  for file in address@hidden; do
    install-info $infodir/$file.gz $infodir/dir 2> /dev/null
  done
}

pre_remove() {
  for file in address@hidden; do
    install-info --delete $infodir/$file.gz $infodir/dir 2> /dev/null
  done
}

I think the install-info command is smart enough to handle the split info files 
itself, so the array "filelist" should not contain files with -1, -2... 
extension.

This is only an example.

Am I right?
Can you check if the affected packages have somthing like this in the install 
file?
