Matthias,

Understanding goes far beyond mere knowledge - understanding *is* the ability 
to solve problems. One's understanding of a situation or problem is only as 
deep as one's (theoretical) ability to act in such a way as to achieve a 
desired outcome. 

A chess grandmaster has a much deeper understanding of chess than a novice. The 
grandmaster is able to solve chess problems of much greater complexity and much 
faster too, because his understanding of the game is deeper.

Likewise, natural language understanding requires solving problems. The 
problem-solving involved with NLP is cross-domain (which is obviously an AGI 
trait). Metaphor and analogy require bridging domains. Disambiguation based on 
subtle context cues requires knowing what information is relevant, which in 
turn requires working causal models... learning new language involves bridging 
concepts in a new domain to known concepts (which is how such an AI could learn 
math). 

So your distinction between understanding and problem-solving is a false one. 
My proof stands :-]

The point is that a
system which is able to understand and learn linguistic knowledge  is not 
necessarily
able to use and apply its knowledge  to  solve problems.
