With just that stacktrace alone, you're probably not going to get very far. Those first 5 lines are stackframes, but there is no context likely due to lack of symbols.
If by trace dump, you mean memory dump, then you have a few options for debugging.
1) You can open the dump in Visual Studio - probably the easiest -- see here: http://msdn.microsoft.com/en-us/library/d5zhxt22.aspx
2) You can open the dump using WinDBG There's a bit of a learning curve, but it is a neat skill to have. I always point folks to Tess's blog to ramp on this. The posts are old, but still relevant: http://blogs.msdn.com/b/tess/archive/2008/02/04/net-debugging-demos-information-and-setup-instructions.aspx
If I were handed this stacktrace, I wouldn't waste a ton of time trying to determine what it means. I'd repro the issue and capture a crash dump and use one of the techniques above to determine root cause.
