Ping? For clarity: the main effect of this bug is that dh_fixperms will
not fix permissions of *.pm files under $Config{vendorarch} (currently
/usr/lib/perl5) anymore. (A secondary effect is that dh_perl will not
remove empty directories under $Config{vendorarch}.)

Given that all the packages having files under $Config{vendorarch} will
be rebuilt with the Perl 5.20 transition hopefully next week, this
will bite all of them that are currently relying on this functionality
in one go.

I went through my build logs and found 18 packages containing files
with non-standard permissions under $Config{vendorarch} when built with
perl_5.20.0-1:

  exactimage_0.8.9-6
  libapache-authenhook-perl_2.00-04+pristine-5
  libapache-db-perl_0.14-4
  libauthen-sasl-cyrus-perl_0.13-server-10
  libclone-perl_0.37-1
  libdate-simple-perl_3.0300-1
  libfilesys-smbclient-perl_3.2-2
  libforks-perl_0.34-2
  libfuse-perl_0.16.1-1
  libmath-bigint-gmp-perl_1.38-1
  libmath-int64-perl_0.30-2
  libnet-arp-perl_1.0.8-1
  libnet-idn-encode-perl_2.200-1
  libsgml-parser-opensp-perl_0.994-3
  libtest-leaktrace-perl_0.14-2
  libtfbs-perl_0.6.0+dfsg-1
  libtk-tablematrix-perl_1.23-6
  libxml-bare-perl_0.53-1

(Changing usr/share/perl5 to $Config{vendorlib} in my patch is not
 necessary for this transition. It's sort of overkill but shouldn't
 hurt either.)
