            Bug ID: 121292
           Summary: LibreOffice Writer Deleting Formulas From Documents
           Product: LibreOffice
           Version: 6.1.3.2 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Formula Editor
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: davidjohnsonda at gmail.com

Description:
I use LibreOffice for school, as I type all assignments. This includes
assignments with a large amount of math. In math-based assignments, I use the
formula editor for mathematical symbols. I often will have a few hundred
formulas in a single document. Recently, however, I have noticed that in some
documents (it has happened on 2 so far), a large proportion of the formulas get
deleted and replaced with "Object n" labels where n is some positive integer.
Looking in the .odt file, I see that the folder for the deleted objects has
vanished. On the most recent document, I was attempting to export it as a PDF
immediately before the issue occurred. It said that there was a "General
Input/Output Error," despite the fact that other processes under the same user
account could create and edit files in the same directory as I was attempting
to create a PDF. After I saw this error occurring, after multiple export
attempts, I closed and re-opened the file to find my formulas missing. I have
attached this document, after the error. Unfortunately, I do not have a copy of
the document from before the error. In both of the documents in which the error
occurred, I have images of mathematical expressions or equations from WxMaxima
in the document. To embed these images, I selected the appropriate text in
WxMaxima, right clicked, clicked copy as image and then CTRL+V'd it into
LibreOffice.

Steps to Reproduce:
1. Create a document
2. Add a bunch of formulas
3. Embed a WxMaxima formula a described above
4. Continue adding formulas
5. Open and close the document. It may or may not experience the issue.

Actual Results:
Formulas a missing

Expected Results:
Formulas are intact


Reproducible: Sometimes


User Profile Reset: No


OpenGL enabled: Yes

Additional Info:
Linux: Arch Linux
Linux Kernel: 4.18.16-arch1-1-ARCH
CPU architecture: x86_64
OpenGL system: Nvidia proprietary drivers for GTX 1070m
