Hi,

When trying to use protocol handlers under a snap build created with electron builder, the dbus call required for the launched instance to pass the schema parameters to the main electron instance does not work due to: dbus-send: /snap/bitwarden/x13/lib/x86_64-linux-gnu/libdbus-1.so.3: version LIBDBUS_PRIVATE_1.12.20 not found (required by dbus-send). All other distribution mechanisms (AppImage, Flatpak[using electron-builder .deb)) work fine for the same build. Confinement is strict, and the base is core22 (electron-builder.json).

This is still an issue.

I did some digging on this. In core22, the dbus-send executable - needed for the protocol handler - is linked (correctly) against LIBDBUS_PRIVATE_1.12.20. However, building the app with electron builder copies an libdbus shared object into resulting app's snap layer. Libdbus then tries to load the app's libdbus, which has a mismatched LIBDBUS_PRIVATE (1.12.2).

This can be fixed by wrapping launching the app with an LD_PRELOAD to load the base images libdbus.

I'm honestly unsure if this is a misconfiguration in Bitwarden's electron-builder configuration, or a bug in electron builder.
