Would you mind sharing, somehow, a bug tracker or mention it somewhere so that I (or we) can know when it is resolved?

Thanks again!

That explains why in the recovery process the slide I was editing disappeared.

I confirm that I can reproduce the bug with your test case.

Thank you a lot for working on this!

OK, I was able to track down the issue using break points in TexMaths and I found that the problem is in Impress.

In TexMaths, when editing an equation, the old image is cut and the new is pasted. But there is a problem in Impress that breaks this process and is responsible for the crash.

I found a way to reduce the problem to a simple test, without needing TexMaths. Here are the steps:

1) Open the attached test.odp

2) In slide 1, select the image (world), then press Ctrl-C => image is copied to the clipboard

3) Go to slide 2 and press Ctrl-V => slide 1 image (world) is pasted over slide 2 image (person)

4) Still on slide 2, select top image (world) without moving it and press Ctrl-X => image (world) should be cut to clipboard

We can observe that at step4, the whole slide 2 is cut to clipboard instead of simply the top image. This is the bug that makes Impress crash when using TexMaths, because slide 2 has disappeared...

Note that if you move the top image by one pixel (as you already observed) before pressing Ctrl-X, then the issue does not appear. Also, I found that the issue happens with either png or svg images.

Could you check you can reproduce the issue? And then I'll make a bug report to the LibreOffice team.

Yay! I have not tried it on Windows, but it happens both on Mac and Linux. Let me know if you need further information.

OK, now I managed to reproduce the bug! I don't know why I couldn't because I don't see what has change in the steps I do...
