It seems bug #134858 marked as fix released (and also originally it's about update-manager and not apt-get), though I still have got this bug, so I've decided to include my comment here as well (with some modifications):

I've also got this bug, it's ubuntu gutsy on AMD64 (but I've seen this on an i386 box too at my workplace, with the same version numbers), version of apt package is 0.7.6ubuntu12, version of dpkg is 1.14.5ubuntu16. From time to time using "apt-get" causes to "freeze", I can see process "dpkg" in defunct state with command ps. It seems it's just after unpacking packages, since killing apt-get than running "dpkg --configure -a" does the trick (eg furthet "apt-get dist-upgrade" does not find any more task to do).

Also (don't it's related or not) I've discovered that I can't stop apt-get (when unpacking packages) with CTRL-Z even before the freeze however I've used this to stop installing packages for a while if I need more disk I/O bandwidth for an urgent task or such (I've got very slow disk ....) which can be continued with command 'fg' from the shell where I had ran apt-get from.

As I've written in my latter comment of mine, even CTRL-C does not work. I've met with this problem from issuing apt-get from gnome-terminal and text console as well (without starting X) if it counts ...
