Settings active tab error (cause problem with other plugins)

I found a problem in my site with this plugin that makes other plugins to stop working due a javascript error.

The problem comes in the settings.js when trying to detect the active tab (at the beginning of the file) it reads it from localstorage using key “activetab”:

activetab = localStorage.getItem("activetab");

as activetab is a generic name I think it was written in other plugin and read here. Then the value of activetab is not any jquery valid id. Making the line

if (activetab != '' && $(activetab).length ) {

to fail and stop javascript execution.

I set a workaround for that:

...
        if (typeof(localStorage) != 'undefined' ) {
            activetab = localStorage.getItem("activetab");
        }
// <XWOLF> test localstorage is jquery valid 
try{
$(activetab);
}catch(e){
activetab='';
}
// </XWOLF>
        if (activetab != '' && $(activetab).length ) {
            $(activetab).fadeIn();
        } else {
...

I also recommend to use some prefix for this plugin on the local storage to avoid name collision.
