Package: apt
Version: 0.8.6
Severity: serious
Okay, this was a WTF moment here. I was playing with python-visual on my HTPC
and when done wanted to remove all the cruft again. So I ran
apt-get remove --purge "... the packages ..."
and it removed me half of my system (and as apt ignores ^C at the moemnt,
i was not amused :()
Here is what happens when I try to re-remove the packages from my system:
eiga:~# apt-get remove --purge libblas3gf libboost-python1.42.0 libboost-signals1.42.0 libboost-thread1.42.0 libcairomm-1.0-1 libgfortran3 libglade2-0 libglademm-2.4-1c2a libglibmm-2.4-1c2a libgtkglext1 libgtkglextmm-x11-1.2-0 libgtkmm-2.4-1c2a liblapack3gf libmpfr4 libpangomm-1.4-1 python-numpy python-visual

Use 'apt-get autoremove' to remove them.
The following packages will be REMOVED:
build-essential* cpp* cpp-4.3* cpp-4.4* dkms* g++* g++-4.4* gcc* gcc-4.3* gcc-4.4* libmpfr4* libstdc++6-4.4-dev* linux-headers-2.6-amd64* linux-headers-2.6.32-5-amd64*

0 upgraded, 0 newly installed, 22 to remove and 0 not upgraded.
After this operation, 136 MB disk space will be freed.
Do you want to continue [Y/n]? ^C
None of the requested packages are installed and apt still tries to remove
something completelly different (rendering the system unusable as its only
purpose is running xbmc :))

I was near to the point to say that this is a feature rather than a bug -
its not a good idea to kill a running dpkg process and APT prints out
what it does in all glory details BEFORE doing it and even asks for
confirmation… its not like a "rm -r --no-preserve-root /" or some dd
style stuff…
( In my humble opinion it is way cleaner to let dpkg do its dirty job if it is
already running and just installing all i need again after dpkg finishes, but
maybe my problem is that i am not so fast at typing a 'y'… )

Don't shoot the messenger!
You requested to remove libmpfr4 which is a hard-dependency of the gcc-family.
x11-utils depends on cpp, which is a dependency of xbmc-bin from which you
can properly guess why the rest of xbmc is removed.
The option -o Debug::pkgProblemResolver=1 will tell you all the glory
details if you are really interested in the complete dependency chain.
If the dependency chain is a sane one is another point, but completely out of
scope for APT, it does what it was asked for so i close this serious PEBKAC now…
Best regards
