我在.NET 4.0中使用WebBrowser控件并且随机崩溃。虽然应用程序的使用完全相同，但应用程序崩溃的时间会有所不同。
以下是Windows提供的问题描述：
<EventType>APPCRASH</EventType>
<Parameter0>MyApp.vshost.exe</Parameter0>
<Parameter1>11.0.50727.1</Parameter1>
<Parameter2>5011d445</Parameter2>
<Parameter3>mshtml.dll</Parameter3>
<Parameter4>9.0.8112.16476</Parameter4>
<Parameter5>5126ee6c</Parameter5>
<Parameter6>c0000005</Parameter6>
<Parameter7>00262cd4</Parameter7>
如何调试此问题？我尝试打开转储文件，我得到的堆栈跟踪没什么用处（是吗？）：
