The crash is clearly related to the nouveau driver, probably because GStreamer
uses hardware decoding. This explains why the crash only happens on cw-gtx560
since that's the TestBot's only NVidia machine.

Note also that the crash did not happen before the commit below:

commit 87e4c289e46701c6f582e95c330eefb6fc5ec68a

Unfortunately there is no backtrace but adding traces helps reconstruct a
partial call stack:

In test_sync_reader_streaming():
tests/wmvcore.c:605:    hr = IWMSyncReader_Close(reader);  /* first call */
wm_syncreader.c:64:    return wm_reader_close(&reader->reader);
wm_reader.c:1508: wg_parser_disconnect(reader->wg_parser);
