Fix crash in status bar ticker.

        final Segment newSegment = new Segment(n, icon, n.notification.tickerText);

        // If there's already a notification schedule for this package and id, remove it.

        for (int i=0; i<initialCount; i++) {

        for (int i=0; i<mSegments.size(); i++) {

            Segment seg = mSegments.get(i);

            if (n.id == seg.notification.id && n.pkg.equals(seg.notification.pkg)) {

                // just update that one to use this new data instead

                mSegments.remove(i);

                mSegments.remove(i--); // restart iteration here

            }

        }
