TypeError: undefined is not a function

maybe leaving it out then?

But doesn't the spec for own() say that the argument needs a destroy()/remove()/cancel() method?

not really: own() Defined by dijit/Destroyable Track specified handles and remove/destroy them when this instance is destroyed, unless they were already removed/destroyed manually.

Well, it would be nice if it is more robust. You can decide to set it as invalid as we removed the own(objectstore) call. But maybe there are more of these calls in our framework, we did a lot of own()ing since there are several memory leaks in IE when running dojo some hours without page reload.

I have no idea how it could be "more robust". doesn't have a destroy()-like method, so it just gets garbage collected by the VM.

Note that the API documentation for Destroyable states that the handle needs a destroy method:

Call this.own(...) on list of handles (returned from dojo/aspect, dojo/on, dojo/Stateful::watch, or any class (including widgets) with a destroyRecursive() or destroy() method. Then call destroy() later to destroy this instance and release the resources.

The reference doc does need to be updated though, so I did that now in
