Package: cruft-ng
Version: 0.4.52
Severity: normal
X-Debbugs-Cc: [email protected]
I had created a dpkg local diversion using the command -
dpkg-divert --divert /etc/PackageKit/20packagekit.distrib --rename
/etc/apt/apt.conf.d/20packagekit
The output of the command "dpkg-divert --list" command is now -
diversion of /usr/share/dict/words to
/usr/share/dict/words.pre-dictionaries-common by dictionaries-common
diversion of /usr/share/man/man1/sh.1.gz to /usr/share/man/man1/sh.distrib.1.gz
by dash
local diversion of /etc/apt/apt.conf.d/20packagekit to
/etc/PackageKit/20packagekit.distrib
diversion of /usr/bin/firefox to /usr/bin/firefox.real by firefox-esr
diversion of /bin/sh to /bin/sh.distrib by dash
When I run cruft-ng version 0.4.52 on the system it crashes with Segmentation
fault
Below is the relevant part of the output (in gdb, with DEBUG variable set to 1)
Note that the output of "dpkg-divert --list" does not show a package name for
the local diversion. The code parsing the output in dpkg_open() always assumes
that there is one. (If the dpkg local diversion is removed, cruft-ng completes
successfully)
