[Bug 491151] [NEW] vlc:Modified Graphic Equalizer sliders not updated after same preset is selected

[Erik B. Andersen]

Public bug reported:

Binary package hint: vlc

If the equalizer in vlc is turned on, a preset is set, the equalizer
sliders adjusted, a the same preset is reselected, the sliders are not
set to the preset, while the sound is reset to the preset.

To reproduce:

1.   Start a song playing with vlc
2.   Open the Tools > Effects and Filters menu item.
3.   Go to the Audio Effects tab, and then go to the Graphic Equalizer tab.
4.   Check Enable and 2 Pass
5.   For the Preset select Flat
6.   Move the first 5 sliders to the minimum, and the last 5 to the maximum.
7.   Select the flat preset again.
8.   Notice the sliders do not move. Also notice the sound changes back to what it would be like played with the flat preset.
9.   Adjust Every slider by the tiniest amount. 
10. Notice the sound jumps back to the non-flat sound equalization and that the sliders are back in sync with what is really happing with the sound.
11. Repeat steps 5-10 with a different equalizer (for both times), notice how the same thing happens
12. Repeat steps 5-10 but use a different preset in step 7 than in step 5. Notice how the sliders move like when you select the new preset, and are in sync with what is really happening with the sound.

What I expected to happen:
I expected that after I adjusted the sliders and re-selected the preset, vlc would set it back to the preset defaults, and the sliders would show that change. Instead, it resets the sound but not the GUI sliders.
