Title:
  gstreamer 0.10 apps prematurely stop parsing some flac files

Status in gst-plugins-good0.10 package in Ubuntu:
  Confirmed

Bug description:
  Gstreamer 0.10 stops processing certain flac files before their end is
  reached. When it happens, no error condition is reported. It fails
  silently, as if the file was truncated.

  This affects all applications that use gstreamer0.10-plugins-good,
  including clementine, exaile, soundconverter, and many others.

  Upstream git branch 0.10 has had patches since 2012 that seem to fix
  the problem, but they have not yet made it into an official 0.10.x
  release. The relevant changesets are:

  5881603 flacparse: avoid indefinite extended search for frame end if possible
  440d703 flacparse: perform additional frame crc check if applicable
  32cddf6 flacparse: avoid some more frame misparsing by additional header sanity check

  The fixes are present in gstreamer 1.0, but applications that still
  depend on 0.10 (either directly or through python-gst) remain broken.
  This seems like a good reason to apply the fixes to 0.10.
