WPF App crash: faulting module mscorwks.dll

On some computers that have Win XP SP3 with .NET Framework 3.5 SP1 installed, my WPF application sometimes crashes. In the Application logs I found these two errors:

1. Faulting application mdp.ser开发者_Go百科ve.exe, version 2.1.215.0, stamp 4e302d6a, faulting module mscorwks.dll, version 2.0.50727.3623, stamp 4d8c187e, debug? 0, fault address 0x000a20c1. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

2. .NET Runtime version 2.0.50727.3623 - Fatal Execution Engine Error (7A0BC58E) (80131506) For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

Any ideas or suggestions? Thank You.
