           Summary: [alsasink] crash at end of playing this file
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins

i used the 12-Toxicity.mpc file from ronald's FTP (in /musepack)

it is an APE tagged musepack file, so to play it, i tried the following pipeline :
filesrc location=12-Toxicity.mpc ! apedemux ! musepackdec ! alsasink

the crash happens just after gst-launch -v said :
/pipeline0/filesrc0.src: active = FALSE
(and sounds stop a few seconds after)

it played the file fine, but at the end, it segfaulted, got a backtrace :
