Bug Description

Hello,

I'm using Ubuntu 12.04.2 LTS and python-apt 0.8.3ubuntu7. I wrote a small Python program (attached) to install a package. It doesn't have custom fork(), but program behaves like it does.

aleksi@ubuntu-virtual-server:~$ sudo ./test.py

This is a problem with base.InstallProgress (just checked on 0.9.3.3) as well, I haven't looked any closer at it yet, though.

Nobody except you seems to have used this DepCache.commit() The problem is that we do not set the child_pid attribute of the progress handler, thus failing. If we do this, we hit some more bugs, which I fixed in the attached patch.

Fixed in Debian git, commits:

I'll upload 0.9.3.4 to Debian soon then, and we can sync to Ubuntu afterwards.
