Title:
  Lintian uses a lot of time doing analyzing of HTML pages in package

Status in lintian package in Ubuntu:
  Confirmed

Bug description:
  Reproduced by downloading this package:
  http://downloads.typesafe.com/scala/2.11.0/scala-2.11.0.deb and
  running lintian:

  After that output, lintian hangs using 100% CPU.

  Ah, after running strace, I see that it is actually analyzing the HTML
  files, probably searching for more JS libs:
