NPE When using a merged segment

I have the same problem with a merged segment. I had a look
with luke at 
the index and it seems that the indexer puts the old segment
names in 
there instead of the name of the merged segment. I'm not
sure if I did 
something wrong or if this is a bug.

I think it is a bug. It saves the old segment name instead
of replacing it
with the new segment name
