[Eric] Ruby error with $stdin.gets

[Eric]

I am trying to use eric4 4.4.2 with ruby scripts and the ones that use $stdin.gets fail under eric4.
This seems to be because under eric4 $stdin is of type AsyncFile instead of the normal type IO and
unfortunately AsyncFile lacks a public gets method, For example, when I run a ruby script with this
single line in it:

$stdin.gets

I get the following error info on the eric4 Shell window:
ruby 1.8.7 (2009-06-12) [i486-linux] on g2s, No Qt-Version
>>> /usr/lib/python2.6/dist-packages/eric4/DebugClients/Ruby/DebugClientBaseModule.rb:172:in

     from /usr/lib/python2.6/dist-packages/eric4/DebugClients/Ruby/DebugClient.rb:44

This looks like an eric4 bug to me. I am currently working around this problem by using
$stdin.readline instead of $stdin.gets.
