c# error in kernelbase.dll on .NET 2.0

I'm getting the following error for my application on some machines. I'm wandering what the best methods are for debugging this issue - nothing is being logged so it looks like the fault is happening outside my codebase (no doubt caused by something I've done!)

Log Name: Application Source: Application Error Date: 25/01/2012 2:23:29 PM Event ID: 1000 Task Category: (100) Level: Error Keywords:

Error code 0xe0434f4d is for CLR exceptions.

To debug, you may learn about crash dumps and WinDbg. Below is an example for ASP.NET, but if you know how to capture a crash dump for other kinds of .NET applications, the dump analysis workflow is the same,
