OK, confirmed here with GStreamer backend. It wouldn't do it with the
Xine backend (even although it uses the same PA code as part of my

Something is obviously exposed in the gstreamer backend that triggers
this problem. The important bit of debug so far seems to be:

"PGST(1): Error: pulsesink.c(290): gst_pulsering_is_dead ():
Message:Disconnected: OK (GStreamer encountered a general resource
error.) Code:1"

I'll try and get this fixed.

I'll track it on https://qa.mandriva.com/show_bug.cgi?id=56807 (if you'd
prefer an upstream kde bug, please feel free to open it and reference
the mdv one and I'll work on it directly instead... doesn't make much
odds at the end of the day tho'!)

Thanks for getting a nice test case :)
