tracker-extract frequently crashes with SIGSEGV (Ubuntu 15.10)

Cannot provide any details about possible cause, but tracker-extract crashes about once a day or once per bootup with this message.

Maybe I have a corrupted / malformed file somewhere - dont know how I can find out what it is that it is failing to process?

libgst for me points to a malformed / unexpected video or image file that it is trying to process.

Please check it out; this keeps coming back frequently.
