Image::Magick causes request to hang

[patspam]

app.psgi

use Image::Magick;
my $handler = sub {
return [ 200, [ "Content-Type" => "text/plain", "Content-Length" => 11 ], [ "Hello World" ] ];
};

Followed by:
plackup -s Mongrel2 --send_spec=tcp://127.0.0.1:9993 --send_ident=D807E984-AC0B-11DF-979C-3C4975AD5E34 --recv_spec=tcp://127.0.0.1:9992 --recv_ident=E80576A8-AC0B-11DF-A841-3D4975AD5E34

Causes the request to time out, at least on my laptop (Ubuntu 10.04, Perl 5.10.1, Plack::Handler::Mongrel2 0.01000_02)
