I'm not sure this is correct. I think it *does* need documentation in

It is related to this change in Perl 5.18:
http://blogs.perl.org/users/tony_cook/2013/02/perl-io-on-scalars.html
I think while it might *seem* too simple it really is the proper fix for OTRS.
it's fixed in rel-3_2:
https://github.com/OTRS/otrs/commit/3200f38e4ece3b73c1d8f98642b0bf30f5e39043
