WebGL Exception XML deserialize

Hello folks,

[edit 2]
I can confirm this exception gets thrown on every XML deserialize i have (so affects multiple classes), seem to more a generic problem....

[edit]
Problem is only on WebGL, all other platforms work as expected.

I'v been working on this problem for some time now and haven't made any progress.
In short i get an exception when i try to deserialize an textasset from an assetbundle, but this happens in a weird situation :

When i make a WebGL build with with exception handling other then none, i get no exception what so ever, all works as expected.

When i make a WebGL build with no exception handling i get an exception. << thats weird huh

i'm manually editing the generated .JS file and adding console log at "cxa_throw"
That way i can extract a stack trace, but that hasn't helped my very much.

XML Deserialize code :

Code (CSharp):

1.  
2. public static T FromXml<T>(this string xml)
3.         {
4.             var s = new XmlSerializer(typeof(T));
5.             using (var reader = new StringReader(@xml))
6.             {
7.                 var obj = s.Deserialize(reader);
8.                 return (T)obj;
9.             }
10.         }
11.  

Exception:

Okeuh, seems logical, any way to capture such exceptions ? so that my webGL dont crashes when i disable exception handling? it try the try{}catch{} but that did not help.. .?

im using standard .net btw:
using System.Xml;
using System.Xml.Serialization;
