long run gstreamer stops working without message

[Robert Krakora]

Sorry, did not read down far enough on your bug report...

The bug was tested and confirmed on :
* several computers
* several soundcards (usb Muse Pocket LT3, pci Audigy CA0106, internal Intel
82801, Nvidia MCP51, some Realtek chip)
* several alsa build
* several linux build (2.6.32 → 3.2.0), rt-kernels or not rt-kernels
* several Gstreamer versions (0.10 → 1.0)
* some distros (Debian Squeeze, Wheezy, Sid, Ubuntu 12.10)
