If we have a password / username available for a certain server we will use it 
to prevent an extra round-trip.

Yes, I have seen this before but it wasn't really clear to me when that 
happened and couldn't reproduce it.

I think it did it wrong for quite some time, but a recent change might be 
responsible for the segfaults.

Does it help if you change 2189 to:
      if ( checkCachedAuthentication( info ) && !info.digestInfo.isEmpty())
