Arithmetic exception (SIGFPE) crash on pulse-bridge when trying to play song with Rhythmbox
I'm not entirely sure why pulse-bridge is involved here, but whenever I try to play something with Rhythmbox, pipewire-media-session crashes.
Backtrace:
Program terminated with signal SIGFPE, Arithmetic exception.

This value is used at attr->maxlength -= attr->maxlength % frame_size. The C spec says that mod with zero is undefined.
The full backtrace is:
