I already understood that the first time. However it takes me some time to 
peal of the unnessary parts to create a test case, since it happens during 
streaming of a date time when a facet is set. However from the Date.Time code 
one can clearly see that it is incorrect. This is only allowed if the 
specifications explicitly state that the format string may not be empty.

I got an error about an invalid certificate, but maybe I will give it a try.
