Dropping ARCHIVE table fails to remove ARN

[Dreas van Donselaar]

When dropping an ARCHIVE engine table (e.g. the one uploaded related to launchpad 881383), the .ARN file does not get removed:
==================
MariaDB [database]> drop table table;
Query OK, 0 rows affected (0.04 sec)

MariaDB [database]>

$ ls -lah | grep table
-rw-rw---- 1 mysql mysql 50M 2011-10-25 14:05 table.ARN
$
==================

Running MariaDB 5.2.9
