The crash is in psimedia plugin. I don't know if it is a problem with psimedia or gstreamer. Currently I had to disable (sorokin@158062d) psimedia to get a working psi.

Can you post strace log?

[yokto]

I would suggest just disabling psimedia. The source from which psimedia is taken is not maintained (last commit 2012). In psi-plus there is still some activity. See https://github.com/psi-plus/psimedia.

I could write a patch if disabling psimedia is an acceptable solution.

@yokto, sounds good to me
