Add-in creates moc file for a file it should not

Normally, the Add-in creates a moc file when ever you put an include like #include "moc_xxx.cpp" in a source file. It does not check, whether or not the include occurs inside a string like: QString = "#include \"moc_xxx.cpp\""

I have written a application which generates some code automatically. When I edit the source file of this application every time I save the source file the Add-in creates a moc file for this source file - which is just kind of annoying in VS 2008. With VS 2010 there is a real problem because VS 2010 would not load a project which contains the same file more than once...
