Bug#1085289: perl breaks backuppc autopkgtest: no ping response from localhost

[Paul Gevers]

Source: perl, backuppc
Control: found -1 perl/5.40.0-6
Control: found -1 backuppc/4.4.0-10

Dear maintainer(s),

With a recent upload of perl the autopkgtest of backuppc fails in 
testing when that autopkgtest is run with the binary packages of perl 
from unstable. It passes when run with only packages from testing. In 
tabular form:

                        pass            fail
perl                   from testing    5.40.0-6
backuppc               from testing    4.4.0-10
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of perl to testing 
[1]. Due to the nature of this issue, I filed this bug report against 
both packages. Can you please investigate the situation and reassign the 
bug to the right package?
