[otrs] Modification of a read-only value attempted at /usr/lib/perl5/Net/DNS/Question.pm line 47.

Hi all... I have been playing with OTRS and having great success. I recently installed Debian lenny (testing) and installed OTRS. When I try to send an email, I got this error: Modification of a read-only value attempted at /usr/lib/perl5/Net/DNS/Question.pm line 47. I saw that there was a bug on this in bugzilla, number 2017: http://bugs.otrs.org/show_bug.cgi?id=2017 However, I don't know how to apply that patch. Can someone help? If I patch this perl module, will other PERL apps that use it break? Thanks...
