Lintian calls undeclared "fail" subroutine in certain conditions and crashes

[Toby Corkindale]

Binary package hint: lintian

Lintian 2.5.0 tries to call a "fail()" subroutine in certain conditions, however no such routine has ever been declared, and so the code crashes.

For example, try using the --tags-from-file or --suppress-tags-from-file command-line options with a file that doesn't exist.
Command-line:
lintian --tags-from-file slkfjsf
Result:
Undefined subroutine &main::fail called at /usr/bin/lintian line 283.

This is 2.5.0~rc2ubuntu3

---------------
lintian (2.5.1ubuntu1) oneiric; urgency=low

  * Merge from Debian unstable (LP: #798513). Remaining changes:
    - Don't warn about a symlinked changelog file in Ubuntu due to CDBS.
    - Add no-upstream-changelog tag to cruft-general-test-suite,
      cruft-general-upstream, cruft-upstream-binaries, fields-no-homepage,
      patch-systems-no-patch-system tests.
    - checks/changelog-file.desc, testset/tags.libbaz: Drop
      debian-changelog-file-is-a-symlink tag.
    - t/tests/changelog-file-symlink, t/tests/init.d-symlink: Drop these tests.
    - checks/init.d: fix LP: #496798 again; upstream only took part of our
      patch and the rest of the fix was dropped in the last merge; per
      maintainer's comments in Debian bug #569492, Ubuntu will need to
      carry this fix for the time being
    - Add wrong-name-for-upstream-changelog tag to changelog-file-extra-upstream
      test.
    - t/tests/fields-multi-arch: Do not test invalid Multi-Arch field,
      because dpkg-deb will already fail.
    - Drop debug-symbols-directly-in-usr-lib-debug from binaries-general.
  * Dropped changes:
    - Prefer libtest-simple-perl (>= 0.93) to perl (>= 5.12).
  * Cherry-pick 5d5a40f from upstream to fix tests broken by 3.8.1 becoming
    ancient earlier this week. (Thanks to Niels Thykier)
