GWT doesn't work in Internet Explorer 8

Today I try to compile my first GWT project (using Eclipse). It has default 'en' location and also 'bg' location. I'm using ui.xml files with corresponding properties files.

The only problem that I have is that project doesn't work in Internet Explorer 8. No problems with Firefox and Chrome. The start screen is ok, but when I upload file to my servlet and receive the response JSON something is happening and I get this JS error

Webpage error details

The row with error is:

function Ox(a,b){var c,d;c=eval(b.a);d=Gv(new Bv);d.d.innerHTML=FD;(fd(),d.d).innerText=KH;Mx(a,c,d);Uu(a.d);Zv(a.d.g,d);Pv(d,true,true)}

What I have to do know?

P.S. The error is happening no mater what localization version I open in IE

The problem was in my native javascript source code, not the source compiled from GWT. In fact the problem was syntax error in JSON that is generated from my servlet.

I used to put comma after each array element, no mater is it last or not (like PHP arrays)

[
  {"a": "b"},
  {"a": "b"},
  {"a": "b"},
  {"a": "b"}, <- invalid comma separator
]

The Firefox and Chrome understand this, but eval in Internet Explorer is failing
