DlgPrefEq segfault while setting up EQ selectors

Here is the backtrace :

This error occured after a friend of mine tried to launch Mixxx 1.11 (I don't use it for a while).
Mixxx then stopped to start.

To be able to play musique I had to set a custom settingsPath.

Added a band-aid in to prevent the segfault though I don't see how this happened. The code in DlgPrefEq could use a rewrite.

Jean -- do you still have the old profile that caused this?

Could you paste the mixxx.cfg and verify that it doesn't segfault with the fix in master?

[Jean Claveau (jean-claveau-g)]

Here is my config.

And averything works with the last fix, thanks! :)
