Seems that I've found regression in 1.0.

I've created 1s mono sine in audacity. I've tried to encode it with 0.10 and
1.0:

gst-launch-0.10 filesrc location=sine.wav ! decodebin ! audioconvert ! flacenc
! oggmux ! filesink location=sine-flac-encoded-with-0.10.ogg

gst-launch-1.0 filesrc location=sine.wav ! decodebin ! audioconvert ! flacenc !
oggmux ! filesink location=sine-flac-encoded-with-1.0.ogg

marcin at marcin:~/bug$ ls -l
razem 120
-rw-rw-r-- 1 marcin marcin 27346 sie 28 22:51 sine-flac-encoded-with-0.10.ogg
-rw-rw-r-- 1 marcin marcin   156 sie 28 22:51 sine-flac-encoded-with-1.0.ogg
-rw-rw-r-- 1 marcin marcin 88244 sie 28 22:50 sine.wav

Obviously file encoded with 1.0 does not play.

When I create pure FLAC file, it is OK

gst-launch-1.0 filesrc location=sine.wav ! decodebin ! audioconvert ! flacenc !
filesink location=sine-flac-encoded-with-1.0.flac
