In XPostWorker.pm:

my $entry = LJ::Entry->new($u, ditemid => $ditemid);

in Account.pm there is another crosspost() defined which contains the crosspost calls grepped above... *head scratching and more grepping*

Aha! It seems that XPostWorker calls DW::External::Account's crosspost() which calls the one we are actually looking at.

So all of these come from LJ::Entry.

So this bug must be within LJ::Entry.

Meep... that sounds like something that's ... important.
