I have a theory that this crash could be caused by a sudden lack of root priviledges, say bug 436748. Is is possible that losing policykit during the middle of an upgrade could immediately halt the upgrade in such a way that we receive "cannot write to standard output" errors and the PackageKit traceback that we are seeing?

What do you mean by "losing policykit?"

From my unlearned investigation this seems to be related to this change in apt 0.7.22:
"...
  * apt-pkg/deb/dpkgpm.cc:
...
    - send "dpkg-exec" message on the status fd when dpkg is run
..."
I think that method "/usr/lib/python2.6/dist-packages/apt/progress/__init__.py, line 277, in updateInterface" wrongly parses this message as a regular package installation status. The message causing this error is:
"pmstatus:dpkg-exec:0:Running dpkg"

    any of the shipped backends.
