Describe the bug

Title.

All available info is in the core dump file listed in the additional context section.

Steps To Reproduce

Steps to reproduce the behavior:

In a system with PipeWire enabled, connect an Elgato Camlink 4k
See PipeWire's unit core dump on a libcamera function call, enter a crash loop and lose your audio
Despair

Expected behavior

PipeWire should not crash, even if it means not having my camera as a whatever-pipewire-does-with-it when libcamera shits the bed.

Additional context

@halturin Doesn't seem like the same error.

Here's an upstream bug report I ended up filing for the OP btw: https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/2581
