#301 exception in XPatherizerNPP.dll

[Václav Haisman]

I am seeing an exception quite often now:

System.Runtime.InteropServices.COMException was unhandled
Message: An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in mscorlib.dll
Additional information: The handle is invalid. (Exception from HRESULT: 0x80070006 (E_HANDLE))

When I open the process in Visual Studio, I see this call stack:

>   mscorlib.dll!System.Runtime.InteropServices.Marshal.FreeHGlobal(System.IntPtr hglobal)  Unknown
    XPatherizerNPP.dll!NppPluginNET.ClikeStringArray.Dispose()  Unknown
    XPatherizerNPP.dll!NppPluginNET.ClikeStringArray.~ClikeStringArray()    Unknown

This is in this thread: Not Flagged > 0x000057F4 0x00000002 Worker Thread GC Finalizer Thread XPatherizerNPP.dll!NppPluginNET.ClikeStringArray.Dispose Highest

This seems to be happening even when I am not interacting with it.
