perl debugger crashes on hitting tab

[Andrew Stevenson]

With Term::ReadLine::Perl installed run:

perl -d -E 'say("hello world")'

At the debugger prompt type "p $" and hit tab. It dies with:

Debugged program terminated. Use q to quit or R to restart,
use o inhibit_exit to avoid stopping after program termination,
h q, h R or h o to get additional info.

This was fixed in 5.18.3 I understand (https://rt.perl.org/Public/Bug/Display.html?id=120827) but the newest available in the repo for 14.04 is 5.18.2.

I am running:

Description: Ubuntu 14.04.2 LTS
Release: 14.04

and my perl package is 5.18.2-2ubuntu1
