Yep, me too with 2.16.5 and 5.10.0.

I think the way Gtk2::SimpleList::TiedRow::CLEAR() does a $model->clear
invalidates the iters in TiedRow objects in @data.  I suppose

    my @data = @{ $slist->{data} };

is a kind of shallow copy, giving refs to the rows instead of actual
contents, so if the row is deleted then the TiedRow in that @data is no
good.

Perhaps TiedRow might have to use Gtk2::TreeRowReference instead of just
an iter to be safe against its row being deleted (including when all
rows are deleted by ->clear).  It wouldn't make a copy through @data
like this work, but it'd not-work in a better way :-).
