[Bug 910674] [NEW] qapt-deb-installer displays 1000x wrong "Installed Size"

[skierpage]

Public bug reported:

In Kubuntu 11.10 KDE 4.7.3 I downloaded the Google Music Manager app
from https://music.google.com/music/listen#manager_pl as a 64-bit .deb
file . Dolphin's Open With... offered QApt Package Installer, which is
qapt-deb-installer version 1.2.

Its Package Installer window > Details tab shows "Installed Size: 9.5
KiB". That's clearly wrong, it's several orders of magnitude off.

 % dpkg-deb -I /tmp/google-musicmanager-beta_current_amd64.deb
reports
 new debian package, version 2.0.
 size 3033010 bytes: control archive= 4690 bytes.
 ...
 Maintainer: Google Music Team <musicmanager-linux at google.com>
 Installed-Size: 9704
 ...

qapt-deb-installer seems to be interpreting this Installed-Size number
as bytes and converting it to KiB, but that's wrong. I've spent an hour
searching teh IntarWub for Installed-Size and the only hint I've found
of its intent is in deb-substvars(5) which says "If this variable isn't
set dpkg-gencontrol will use du -k debian/tmp to find the default
value." I.e. it is indeed already in K (1024 bytes, kibibytes, KiB,
etc.).

GDebi Package Installer's very similar Details tab  says the same .deb
file is Size: 9704 KiB. So a fix is to just do what gdebi-kde does,
which is display the deb's  Installed-Size followed by "KiB" rather than
(??) performing some units conversion.
