The problem is caused by an IOleCommandTarget implementation which registered with IVsTextView by calling IVsTextView.AddCommandFilter. In the implementation of IOleCommandTarget.Exec, the command ID VSStd2KCmdID.ECMD_LEFTCLICK or VSStd2KCmdID.DOUBLECLICK is being handled.

I would open ILSpy, and open the assemblies contained in %USERPROFILE%\AppData\Local\Microsoft\VisualStudio\12.0\Extensions (recursively). I would then open Microsoft.VisualStudio.OLE.Interop.dll and locate the IOleCommandTarget interface. You can then examine the derived types from that interface for a class whose Exec method handles the commands listed above. Selectively disable the associated extension(s) until you narrow down the culprit.

I'd argue this is just a straight up bug in Visual Studio. Either the SimpleTextViewWindow or VsMouseProcessor class simply aren't properly accounting for the fact that the IWpfTextView could be closed at this point and is throwing.

I'm looking at the decompiled code for 2013 and I can't 100% see where this is happening. But the code path does seem to not be accounting for this possibility

If the handling is performed using an IMouseProcessor instead of an IOleCommandTarget, I'm fairly certain this situation would be avoided. Hopefully if he can track down which extension is using the IOleCommandTarget it could then be updated to use the new interface.

Also, the code in VsMouseProcessor could be updated to check the IsTextViewHostAccessible property.

if (SimpleTextViewWindow != null && SimpleTextViewWindow.IsTextViewHostAccessible)
{
    SimpleTextViewWindow.ClearCommandContext();
}
