[D Haley]

Package: libqhull6
Version: 2012.1-4
Severity: grave
File: libqhull
Justification: renders package unusable

Dear Maintainer,

-dev package appears to contain zero-byte files. Dpkg reports the following

(Reading database ... 260712 files and directories currently installed.)
Preparing to unpack libqhull-dev_2012.1-4_amd64.deb ...
Unpacking libqhull-dev:amd64 (2012.1-4) ...

 Errors were encountered while processing:
  libqhull-dev_2012.1-4_amd64.deb

Attempting to force-all does nothing:

LANG=C sudo dpkg --force-all -i libqhull-dev_2012.1-4_amd64.deb
