Crash on fn key press

[sevonj]

Describe the bug
Pressing the function key causes an instant crash. This happens when a book or a catalog is open. It doesn't occur in the library view.

To Reproduce
Steps to reproduce the behavior:

1. Open a book OR open a catalog
2. Press fn key

Expected behavior
The app should survive a key press.

Screenshots

Version:

• Foliate version: 3.2.0
• OS/Distribution and version: Vanilla OS 2.0
• Desktop environment: Gnome 46
• Installation method: Flatpak (Flathub)

Additional context

So, the device is an old 2013 macbook air with finnish keyboard layout. Either of those things, or both may be relevant. System language is en-us.

I'm inclined to say that this is not our bug because I don't think Foliate is getting any accel string anywhere, much less passing such strings to to anything. On top of that, there's no shortcut specific to the catalogs view.

If it doesn't happen when there's no WebView, it might be a WebKitGTK issue, though one might be able to disprove this if one is able to press fn without crashing other WebKitGTK apps.

It's unfortunate if nothing can be done on this end, since the app has been pretty crashy for me. I also experienced the one where just opening catalogs or books crashes the app, while fiddling with locales, but haven't yet attempted to reproduce it.

[johnfactotum]

Crashing caused by mixed locales is a known Flatpak bug.

I tested fully finnish and fully us-english settings, including keyboard layouts, just in case (full reboots between). That didn't make a difference, so I guess it can be ruled out. Couldn't reproduce the other one.
