Strange jQuery Unrecognized Expression (Syntax error, unrecognized expression: .)

So I have a really weird bug in jQuery 1.11.1 (Compressed).

I have a collapsing div and when I load the page page I am developing on my Mac the I can get this to work perfectly. Thinking the page was ready to be finalised I did a test on good old Windows and it was not working.

I had a look at the console to see why this isn't working and I was presented with the following error"

Uncaught Error: Syntax error, unrecognized expression: . jquery.js:2

So I decided I would look further into what was happening with this error and this is what the console output also displayed upon further inspection.

fb.error jquery.js:2
fb.tokenize jquery.js:2
fb.select jquery.js:2
fb jquery.js:2
m.fn.extend.find jquery.js:2
m.fn.init jquery.js:2
m jquery.js:2

I'm not 100% is there is an issue with this particular version of jQuery or if it is something I am doing.

Here is the code for my collapsing dive.

$('.').click(function(){
    $('.round-details')
});

Any help will be greatly appreciated as this issue is a bit beyond my abilities with jQuery as I am still only learning.

Thanks

Stu :)
