[Bill Allombert <ballombe@debian.org>]

Package: lintian
Version: 2.105.0
Severity: important

Dear Lintian maintainers,

For some reason lintian crashes on the source package at
https://people.debian.org/~ballombe/lintian

(which is very similar to gap-gapdoc in the archive, which works fine).

with
$ lintian gap-gapdoc_1.6.4-1.dsc
