Is this specific to mpv, or are multiple applications crashing in the same way?
The crash could be due to mpv calling pa_threaded_mainloop_unlock() when the
thread doesn't hold the mainloop lock.

Another reason could be that mpv is linked to libpthread-stubs instead of the
normal libpthread implementation. libpthread-stubs has been the reason for
mutex failures in several occasions. What does this command print:

    ldd `which mpv` | grep pthread

I'll attach a patch that should make the crash log a bit more informative. Can
you try it out?
