I no longer have access to an Intel Mac. I got a bug report, and I need help.
aedebug glue iCal '$x = $g->obj(event => gAny, calendar => gAny)->get; print $x->prop("summary")->get; my $t = $x->prop("start date")->get; print $t; print scalar localtime $t'
Then send me the entire output (there will be quite a bit of debugging output), either here (use the "Code" posting format), or via e-mail.
Update baud helped me out, so now I have a proper diagnosis of the problem, and I don't need further assistance for now. He also helped me uncover another problem that my test case here exposed, that was not in the original. W00t.
