Comment(by mmetz):

 I did some testing and found out that

  * I could only reproduce BUG2 with cache enabled
  * BUG2 occurred only if the path to the node closer to start was
 requested first
  * BUG2 occurred only if the distance or cumulative cost was requested and
 not the actual path

 BUG2 is now fixed in trunk and devbr6, at least I can no longer reproduce
 it, but maybe I have overlooked some special case.
