The document is not corrupt. IT is perfectly fine, the problem is
either in our import code, which just misses sanity checks for quite a
lot of input, or in the string class which can't handle with such
situations at all. Since we have quite a lot of these places in the
import code it might be better to find a solution in the string
class.'m not sure if

I'm not sure if throwing an exception is a good idea in this case as
this might result in exceptions in constructors and even worse in
destructors. It might be a solution to return an empty string or
something like that in these cases or something like that and log it
in a dbgutil build.
