[Pkg-utopia-maintainers] Bug#1012563: wireplumber: right click broken in firefox 100.0.2-1

[Gabriel Corona]

Hi,

I collected some stack traces and apparently the problem happens in 
libcanberra-pulse :

Apparently clicking on a menu triggers a canberra notification which 
goes trough pulseaudio. Looking at canberra source code, it creates a 
pulse audio threaded mainloop which appears to never reach the 
PA_CONTEXT_READY state.
