The problem stems from pw_init() ambiguously exported from both libpipewire= .so and libutil.so. The libgstpipewire.so's plugin_init() calls pw_init() to initialize libpipewire. Since libgstpipewire.so links to both libpipewire.so and libutil.so, on my system it happens to call pw_init exported from libutil.so instead of the libpipewire.so's one. Both exports take two pointers as parameters and the SIGSEGV occurs later on when effectively uninitialized libpipewire starts being used. The backtrace when SIGSEGV actually occurs looks like: Thread 1 received signal SIGSEGV, Segmentation fault.
