This make no difference. I still get the same output. I even tried it with
linitian 2.3.1 with the same result.

Just to note it again: Sometimes lintian works (say every fourth or fifth
attempt) but must of the time it doesn't. Here the output of the attempt that
worked:

$ lintian --check --allow-root -b -d -d -d ghostscript_8.64-5_i386.deb; echo
"Return: $?"

There should be nothing special about my lintian setup. I'm fairly sure about
this because I usually use lintian from within a cowdancer environment, which is
a clean Ubuntu installation, and this lintian call fails as well. (My other test
were run directly on my server and not from within the cowdancer environment.)

Gladly, but I'm not quite sure how and what to provide as debugging output. For
starters I've run lintian (2.2.18 this time) with the "-d" switch:

 $ lintian --check --allow-root --show-overrides -i -b -d
ghostscript_8.64-5_i386.deb
 N: Lintian v2.2.18ubuntu1
 N: Lintian root directory: /usr/share/lintian
 N: Configuration file: /etc/lintianrc
 N: Laboratory:
 N: Archive directory:
 N: Distribution:
 N: Default unpack level: 1
 N: Architecture: any
 N: 
 N: Setting up lab in /tmp/VIcPpbdtdw ...

Return code is still 141. The content of the lab directory is:

 $ ll /tmp/VIcPpbdtdw/*
 /tmp/VIcPpbdtdw/binary:
 total 0

 /tmp/VIcPpbdtdw/info:
 total 0
 -rw-r--r-- 1 root root 0 Dec 25 10:50 binary-packages
 -rw-r--r-- 1 root root 0 Dec 25 10:50 source-packages
 -rw-r--r-- 1 root root 0 Dec 25 10:50 udeb-packages

 /tmp/VIcPpbdtdw/source:
 total 0

 /tmp/VIcPpbdtdw/udeb:
 total 0

I've also tried to run lintian with a non-root user and with fewer parameters:

 #lintian --check -b -d ghostscript_8.64-5_i386.deb

but with the same result.

Problem is still present in version 2.2.18 (see above).
