Facebook Plugin problem on Windows Phone

Unity Engine
,

Hi,
I have a serious issue with the Facebook plugin I am using to integrate the platform’s APIs, this one: Facebook SDK for Unity - Plus Windows Phone 8 - Unity Engine - Unity Discussions
When I make a fb.login() with the mobile phone in landscape mode (even if I force the portrait), when the game gets the focus again it crashes.
There is no problem if I connect maintaining the device in portrait.

No problem if I set-up, in the MainPage.xaml the value “Portrait” or “Landscape” for the SupportedOrientations variable. The problem occurs when its value is “PortraitOrLandscape”

I set up the debugger in native, here it is the output on the exception:

the call stack:

Is that the whole stack trace that you get?
Are you able to reproduce it on WP8.1?
There in debug build you would get much better stack trace.

here it is:

and:

have you got any hint?

So, have you tried WP8.1?

7

of course, I copypasted you the output. See up!

Could you right click on the stack trace and press load symbols? If it asks you for path, point it to :\Editor\Data\PlaybackEngines\metrosupport\Players\WindowsPhone81<CPU_ARCH><BUILD_TYPE>".

here there are (the right folder was in Visual Studio, not in Unity since I am debugging from VS):

Could you post the full stack trace? Althought it starts looking like a bug inside Unity. A bug report would be nice so we could fix it. Also, could you post your Unity version?

Just edited the last response with the full stack trace.
Unity version: 4.5.4f1
