+Summary: alsasink crashes when restarting
+
+In my playing with alsasink I came across this bug. When you set the
+state from GST_STATE_PLAYING to GST_STATE_READY, and then back to
+GST_STATE_PLAYING again, alsasink crashes. Test program attached
+compiling should be easy :) run it with 
+./program ~/some.mp3 alsasink
+
+It'll play 10 seconds of the mp3, and then stop, wait ten seconds and
+crash.
+If you change alsasink to osssink and run again, it'll play 10 seconds,
+wait 10 play 10 seconds, wait 10...etc until you stop it.
+
+Another error with alsasink seems to be that if you disable the timeout,
+it plays the whole song through without problems until near the end when
+it starts dumping 
+** (test-gst-alsa:3079): WARNING **: alsa: poll reports error.
+ constantly.
+Backtrace: (4 is the event type that the event got, I added this myself)
+** (test-gst-alsa:4966): WARNING **: got an event on alsasink 4
+
+Program received signal SIGSEGV, Segmentation fault.
