yes, it behaved a bit odd, ill retest with the new patches tomorrow (need to sleep)
some things i noticed in the previous ones though
it disappeared with some commits in the previous set too
it doesnt happen with ffmpeg
and i have this half useless backtrace:
#0  0x00000000004752cc in dng_decode.isra ()
#1  0x0000000000b73b67 in decode_frame ()
#2  0x00000000008668d7 in decode_receive_frame_internal ()
#3  0x0000000000867488 in avcodec_send_packet ()
#4  0x00000000007c002d in try_decode_frame ()
#5  0x00000000007c8ad8 in avformat_find_stream_info ()
#6  0x00000000004c2b09 in read_thread ()

ill provide better information tomorrow in case it still happens
with the latest set 

Thanks

Many that live deserve death. And some that die deserve life. Can you give
it to them? Then do not be too eager to deal out death in judgement. For
even the very wise cannot see all ends. -- Gandalf
