Can't import pdf files, flatpak version

[fvelsg]

Describe the bug

The main problem is that I try to import pdf files larger than 80 pages, when I do that usually crashes. Showing errors like:

• " Persisting document; path is [PATH HERE] "
• QSortFilterProxyModel: index from wrong model passed to mapToSource
• QAbstractItemView::commitData called with an editor that does not belong to this view

While importing the first one repeats a lot in the terminal until it crashes.

To Reproduce

I use the LTS Fedora 40 workstation version and I installed Openboard from flathub.

1. Go to the main page
2. Click on 'Documents'
3. Click on 'Import'
4. Select the file and click Open

Expected behavior

I expected it to only load the PDF and open it without any problems, because I used the .deb version in Pop_Os and it works perfectly. I had the same problem in Pop_Os while running the flatpak package.

Actual behavior

While importing it will shot the message do force quit the app, there's a possibility of the software open the pdf in the end, but you can't take it for granted

@jbruechert Can you have a look at this?

I don't think it's flatpak related if it only happens with very large PDF files.
