The job labs-toollabs-debian-glue fails; https://integration.wikimedia.org/ci/job/labs-toollabs-debian-glue/101/testReport/ shows that lintian nowadays complains about jquery.js not being a source file in its minified form.
I'll work around that by adding a lintian override. Another approach would be to rely on the libjs-jquery package (1.7.1 compared to our 1.4.2) and then symlink there.
