+Summary: oggdemux: jump or move depends on uninitialised value
+
+This is with 0.8.0.1 with a pipeline like this using gst-launch 
+ 
+ filesrc location="foo.ogg" ! typefind ! spider ! audio/x-raw-int ! 
+fakesink 
+ 
+Reproducable with any ogg file as far as I can see. 
+ 
+Here is the relevant valgrind output:

+(gstoptimalscheduler.c:1164) 
+ 
+ 
+The first block is due to gst_event_new_discontinuous() being called 
+without vararg terminator. Patch attached. 
+ 
+Haven't looked too hard into the other two errors yet (after the 
+re-indentation Baudrillard suddenly seems an attractive thing to read 
+when the choice is between that and gst code ;)). 
+ 
+Cheers
