FS#1203 - Images not saved (dxflib)

I am doing a bit of landscaping and using a (big) ortophoto as one of my layers in order to sanity-check on the ground measurements.

The layer contains a point and the image and nothing else.

The image is a 8MB file: “PNG image data, 4200 x 2980, 8-bit/color RGB, non-interlaced” and it is scaled to 210 coordinate units (meter) horizontally in the drawing.

With approx 50% probability the image disappears during Save, as see for instance in this diff of the DXF file:

The point in the same layer does not similarly disappear, the bug only seems to affect images.

I have seen this bug from version 3.7.5.0 to git as of yesterday (63e06c778926a803bdfbffdf27b8c24d41511072).

I have not been able to correlate the bug with anything.

Looking closer at the DXF file (attached), there seems to be some residuce of attempts to insert images in protected/invisible layers, so this may be some kind of refcounting issue.

(Any chance of getting FreeBSD into the “Operating System” field ?)
