Identical songs have different durations

[Jean-Baptiste Lallement]

mediascanner extract different durations for identical songs stored on SD card and internal storage.

For example, the title below last 79s and 77s depending on where it is stored:
phablet@ubuntu-phablet:~/.cache/upstart$ grep -E -A4 'Added song.*behaviour.mp3' ~/tmp/mediascanner-2.0.log
Added song to backing store: /home/phablet/Music/[2000] Unreasonable Behaviour/05 - Unreasonable behaviour.mp3
 author : 'Laurent Garnier'
 title : Unreasonable behaviour
 album : 'Unreasonable Behaviour'
 duration : 79

Added song to backing store: /media/phablet/Médias SDc/Music/[2000] Unreasonable Behaviour/05 - Unreasonable behaviour.mp3
 author : 'Laurent Garnier'
 title : Unreasonable behaviour
 album : 'Unreasonable Behaviour'
 duration : 77

And it is the same file:
a9a96c769c657fe8563f26dc540464a4 /home/phablet/Music/[2000] Unreasonable Behaviour/05 - Unreasonable behaviour.mp3
a9a96c769c657fe8563f26dc540464a4 /media/phablet/Médias SDc/Music/[2000] Unreasonable Behaviour/05 - Unreasonable behaviour.mp3

The duration reported by mp3info is 79 seconds.

Please run:

gst-discoverer-1.0 <your mp3 file>

on both of these files. If it reports a different duration, please reassign this bug to GStreamer. Thanks.
