Tried that, didn't work.

It's not color-indexed. There has to be some other property of the image or setting in GIMP that blocks or breaks Threshold Alpha settings. If not it has to be a bug.
Can you share an example XCF image (see attachments link at top right), possibly cropped to a small size to fit the 2MB XCF limit?
