It is probably somehow related to Bug 707015.

I've created a malformed Ogg/FLAC file using method mentioned in Bug 707015.

When I try to play it in 1.0 it hangs the pipeline instead of throwing
EOS/Error/whatever. It is very nasty as it can lead to hanging the app as
proper callbacks/messages are never called.

Test in 1.0:

$ LC_ALL=C gst-launch-1.0 -v filesrc
location=sine-440hz-0point8-1sec-q5-ogg.flac ! decodebin ! audioconvert !

Then in hangs until I press Ctrl+C.


The same in 0.10 works OK:

location=sine-440hz-0point8-1sec-q5-ogg.flac ! decodebin ! audioconvert !
