Visual Studio Plugin (1.1.6) crashes Visual Studio (2010)

Hi all

I have a very strange situation: Since I installed the MS Visual Studio Plug-in (1.1.6) for MSVS 2010, the IDE randomly crashes on copy/Paste operations. I turned on logging and got the following message:

Code:

<entry>

    <time>2010/10/11 15:33:59.568</time>
    <type>Error</type>

    <description>System.InvalidCastException: Unable to cast COM object of type &apos;System.__ComObject&apos; to interface type &apos;Microsoft.VisualStudio.TextManager.Interop.IVsTextReplaceEvents&apos;. This operation failed because the QueryInterface call on the COM component for the interface with IID &apos;{CF9928D9-65AE-4319-A446-94ED5C45ECDE}&apos; failed due to the following error: Schnittstelle nicht unterst&#x00FC;tzt (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).&#x000D;&#x000A;   at System.StubHelpers.StubHelpers.GetCOMIPFromRCW(Object objSrc, IntPtr pCPCMD, Boolean&amp; pfNeedsRelease)&#x000D;&#x000A;   at Microsoft.VisualStudio.TextManager.Interop.IVsTextReplaceEvents.OnReplace(ChangeInput[] pCI)&#x000D;&#x000A;   at Microsoft.VisualStudio.Editor.Implementation.VsTextBufferAdapter.OnTextBufferChangedHighPriority(Object sender, TextContentChangedEventArgs e)&#x000D;&#x000A;   at Microsoft.VisualStudio.Text.Utilities.GuardedOperations.RaiseEvent[TArgs](Object sender, EventHandler`1 eventHandlers, TArgs args)</description>

Setup: Windows 7 (32 Bit), MSVS 2010 Ultimate, Qt 4.7 / Plug-In 1.1.6

Any ideas whats wrong?

Cheers,
