Config file overwritten.

Hi,
I have realized that some of the options that you specify in the config file (~/.config/vlc/vlcrc) get overwritten
when modifying the options from the preference menu using the GUI. I am using the latest stable build (gotten from the ppa)

For example:
Using the preference menu I activated the "web" interface, so that the web server starts every time I run VLC.
I want the server to communicate through port 54444 instead of the default (8080). I therefore opened ~/.config/vlc/vlcrc
and set the http-port to the desired value (removing the #, of course).

When I opened VLC it worked as intended.

Later I wanted to activate and configure the Volume normalizer filter. Using the preference from the GUI I activated the filters
and changed some of the related parameters.

I restarted VLC and discovered that the http server no longer worked on port 54444 but on port 8080.

Playing a bit more with the settings I discovered that when I modify the preferences in the GUI, the values for settings that are not available through the Preferences menu (such as the http-port) are reset to their default value.

This seems a bug to me, but before filing a bug report I wanted to know if someone else experiences the same, or if I am doing something wrong.

Thanks a lot in advance for your help!

Best,
Luca
