The SolidWorks Desktop Search iFilter plug-in (sldsearchifilter.dll) constantly throws exceptions causing Windows to halt when a kernel debugger is attached. Below is a stack trace, with your iFilter DLL bolded. When a kernel debugger is not attached, the exception caused by your iFilter is ignored, but always causes a breakpoint (halt) when the debugger is attached. Clearly, your iFilter is broken
