AppImage crashes when searching inside library page

This bug seems to happen only in the AppImage version of the app.

Steps to Reproduce

• Go to a library (no matter if it is the full view or a tag we view).
• Press Ctrl+F (or hit the search button).
• Enter some search term.

The app crashes.

This does not happen inside e.g. a Todo List. It also does not happen in other versions or on other platforms. Even the Flatpak variant seems not to be affected.
