Hello,
I have been trying to get an obelisk server up and running, but keep
running into problems. After some period of time downloading blocks,
the obelisk node begins spewing errors like this one:

ERROR [poller]: Storing block
0000000000000028010d8b756cf7e9cbeb5f7b9925aac3b941f4553ea7483d29:
Matching previous object found

I have tried both with the latest git version and the latest stable
versions (libbitcoin 1.4 and obelisk 0.2 respectively), but keep
running into the same problem.

I have bootstrapped this database using bootstrap.dat and the git
version of the libbitcoin bootstrap program.

My next task is to try a fresh (non-bootstrapped) blockchain download,
but this will obviously take a long time.
