Package: apt

Dear Maintainer,

running "apt-get update; apt-get upgrade" today, I got

- CUT -

- CUT -

Since I didn't want to go through the trouble of an nvidia driver update just
now, I decided to hand-pick some packages to upgrade:

root@torus:~# apt-get install vim libc6 host

Which would have lead to the removal of a large number of i386 packages (including wine and acroread). I thus said

root@torus:~# apt-get install vim libc6 host acroread
Reading package lists... Done
Building dependency tree       
Reading state information... Done
acroread is already the newest version.
Segmentation fault

Checking in more detail with gdb shows:

- CUT -
root@torus:~# gdb /usr/bin/apt-get 
GNU gdb (GDB) 7.4.1-debian
[...]
(gdb) r install vim libc6 host acroread

The backtrace gives:

If you need additional info, like package selections ore coredumps, I can
gladly provide them.
