The problem is not related to tmdoc-expand per se, you can trigger it by exporting files with embedded images to stm; Then, when reloading the stm file, the error is thrown.

And, AFAICT, it is the xOD bytes (ASCII CR) that get dropped in the image data (at least, there are maybe other).

This issue is mentionned in https://savannah.gnu.org/patch/?10164
and I confirm it.

When expanding help articles, if branches contain embedded images TeXmacs tools throw error messages saying they cannot determine the image size and, of course, images cannot be displayed correctly. In this process, the embedded images get extracted to a temporary directory, and one can observe that the images are corrupted at that point (at least png and pdf). For instance pdf files miss a few bytes here and there...

It seems the problem occurs while performing the branch inclusion in tmdoc-expand, when the included tree contains arbitrary binary image data.
