[1] KDE depends on Python !?!
[2] apt-get remove estimates space-to-be-freed badly
The KDE 2.2.2 Woody/unstable box that I'm building ran out of disk
space the other day (already over 900 Mb used, and all I have is gcc,
perl, python, kde, kdevelop and koffice ... jeez).
So I set about removing some stuff - regretfully I decided to remove
Python (I did want to play with it, but I don't need it right now).
I listed what there was installed, and for some reason there are
python 1.5 debs *and* python 2.1 debs (in fact loads of confusing
version numbers). Not really knowing what I was looking at, and
needing to delete something quickly, I tried deleting the 1.5 debs,
only to have apt-get tell me both *kde* and *koffice* would be
*removed* if I went ahead ! :

Huh ? KDE depends on python1.5-base ? Is that correct ?
Well I sure didn't want to do that, so just for the hell of it I tried
deleting some of Python 2.1 instead. Strangely this didn't demand the
deletion of anything else much, so I did it :

So far, so good (nothing seems to be broken), but wait ... look at
those before & after disk space figures :
before removing anything 62644 Kb
apt-get remove says it will free 8735 Kb
after running apt-get remove 80740 Kb
so 18096 Kb was actually freed - not 8735 Kb at all ...
Is apt-get's estimate badly broken ?
