deleteIndex error when input is an array

[bitinn]

$collection->dropIndex(array('count.pin' => -1, '_id' => 1));

this index in particular results in:

[ErrorException]                                                             
MongoCollection::deleteIndex(): The key needs to be either a string or an array

updated issue ticket (initial test was wrong)

current we need to do this instead. not sure if it is intended.

$collection->dropIndex(array(array('count.pin' => -1, '_id' => 1)));

would also be great if deleteindexes() is supported. (simpler down method in migration)
