Document in which searching triggers the bug

Consider the attached document. That is a document in Hebrew, with a ToC. It exhibits another issue (bug 148686), but that should not be relevant for our purposes.

If I:

1. Open the document in LO Writer
2. Open the find toolbar
3. Search for קורה

I get several matches, as I should - but some of the match paragraphs contain upright-rectangle glyphs instead of Hebrew text. I'll attach both the document and a screenshot.

Seen with:

Search results for קורה in find sidebar, in attachment 194035 [details]

Note that the search results also exhibit bug 160998, but that one can be reproduced much more easily.

I reproduce, but there is some randomness.

For me, the content in the input field shows fine at first, but is flipped to placeholder glyphs after a couple of seconds.

The first time I searched, I got placeholder glyphs for the first hit, but not the second hit. Searching multiple times after that, even closing the document in between, I only got placeholder glyphs in the input field.

After closing LibreOffice completely, the behaviour was reset and started its "cycle" again. Maybe caching is involved somehow.

Khushi: can you take a look at this?
