you're right and I did it always like you wrote. I made an static =
initialisation class.
This way I don't get the problems anymore.
If I had done a singleton with reference counting it could be possible =
that someone decrements the count to zero and all things for =
deinitialisation are called and afterwards someone constructs and =
initialises again and gets the error.

So now everything works fine.

Thanks to all for the help.
