I just got
Assertion 'pa_close(m->fd) == 0' failed at pulsecore/shm.c:286, function pa_shm_free(). Aborting.
I only wonder where pulsecore comes from? It seems like a native part of openAL maybe? Maybe Upgrading would help?
However it seems like it comes from a deeper layer, considering Amarok of KDE also has this bug. Do you also use Kubuntu, @grizeldi?
Edit: And yet another crash, this time it even crashed the jvm with a SIGSEV:
