Re: [bdbxml] disappearing default index

Does the file cause a crash if it is loaded using the DB XML shell 
(called "dbxml")? If not, then it is something you are doing wrong in 
your program. If it does, can you please send me the file that causes 
the crash, so that I can attempt to reproduce your error.
