Reviewing the strings returned by lib/dpkg/buffer.c the following patch
should resolve the issue, although this is still not ideal.

Title:
  string matching for dpkg I/O errors in dpkgpm.cc is out of date

Status in “apt” package in Ubuntu:
  New

Bug description:
  The following error strings are no longer returned by dpkg:

     io_errors.push_back(string("failed to read on buffer copy for %s"));
     io_errors.push_back(string("failed in write on buffer copy for %s"));
     io_errors.push_back(string("short read on buffer copy for %s"));

  Subsequently, apport package installation failures are being created
  for these types of crashes and they should not be.  Additionally,
  there is a new error returned by dpkg ("unexpected end of file or
  stream" as seen in bug 1361489) which should also be blocked.
