Maybe the problem is with onLoadInit event handler. You could write a simple testcase for this function. eg. check if the target and the properties of the target could be accesssed inside the onLoadInit function. Maybe Gnash doesn't trigger the onLoadInit handler at proper time, eg. at a too early or too late stage.

Yes, the object is a depth 1, so that makes sense.
I've done a bit more testing today, and the replace_display_object error might just be a symptom of a larger issue I'm having. After the second load of the sub-SWF containing the DataGrid, the destination MovieClip has a width and height of 0 -- and I cannot resize with actionscript.
I verified that when I register my MovieClipLoader listener, the destination clip's size is valid:

If I remove the (empty) DataGrid from frame 4, everything works just fine.
