Package: lintian
Version: 2.5.22ubuntu1
Severity: normal
Tags: patch

Lintian failed to parse an (unofficial) package throwing Perl errors as seen below. A trivial fix is supplied below.

Suggested fix that allows the package in question be parsed:

Hi,

I am closing this as we have waited for moreinfo for two years and have
not seen any reproducer in the wild either.  This is presumed to have
been fixed in 2.5.30 (or before) unless a reproducer is presented that
can show otherwise.

Thanks,
~Niels
