[Debconf-devel] Bug#439763: Bug #439763 Bug#439763: debconf: hangs on puppet installs on preseed install

[Will Aoki]

This started happening on April 8th on most of my wheezy systems. I'm
running apt-get from cfengine, not puppet, but symptoms are otherwise
the same, e.g.:

cfengine:xxxxx:/bin/sh -c 'DEB: (Reading database ... 326575 files and directories currently installed.)
cfengine:xxxxx:/bin/sh -c 'DEB: Preparing to replace openssl 1.0.1e-2+deb7u5 (using .../openssl_1.0.1e-2+deb7u6_amd64.deb) ...
cfengine:xxxxx:/bin/sh -c 'DEB: Unpacking replacement openssl ...
cfengine:xxxxx:/bin/sh -c 'DEB: Processing triggers for man-db ...
cfengine:xxxxx:/bin/sh -c 'DEB: /var/lib/dpkg/info/man-db.postinst: 44: /var/lib/dpkg/info/man-db.postinst: 3: Bad file descriptor
cfengine:xxxxx:/bin/sh -c 'DEB: dpkg: error processing man-db (--unpack):
cfengine:xxxxx:/bin/sh -c 'DEB:  subprocess installed post-installation script returned error exit status 2
cfengine:xxxxx:/bin/sh -c 'DEB: Errors were encountered while processing:
cfengine:xxxxx:/bin/sh -c 'DEB:  man-db
cfengine:xxxxx:/bin/sh -c 'DEB: E: Sub-process /usr/bin/dpkg returned an error code (1)

This hadn't been happening before that date. I haven't identified why it
works on some but not on others -- there isn't supposed to be any
configuration difference between the two groups.
