For some weird reason, whenever I ping a site, I get the following code in my ping window (look at one of my book reviews to see what I'm talking about):

MT::App::Trackback=HASH(0x8276c1c) Use of uninitialized value in exists at /usr/lib/perl5/site_perl/5.6.1/XML/RSS.pm line 1432.

Anyone else see this or know what the problem might be?
