Comment 2 for bug 675398

The log shows that many files are missing in /var/lib/dpkg/info/ and the two packages that fail use ucf. I would not be surprised to learn that more stuff is missing from /var. Thus I suspect this is a failure of ucf when some of his files are unexpectedly missing.

Reassigning to ucf for further investigation. At least ucf could generate a proper error message instead of only exiting with an error code.
