This is what I get after block with a lot of tranasactions:
/usr/local/lib/python2.7/dist-packages/Abe/abe.py in handle_chain(abe=<__main__.Abe instance>, page={'body': ['
Search by address, block .........}, 'title': u'AuroraCoin'})
486 seconds = int(seconds)
487 satoshis = int(satoshis)
=> 488 ss = int(ss)
489 total_ss = int(total_ss)
490
ss = None, builtin int =
You can edit Abe/abe.py and replace "int(ss)" with "None if ss is None else int(ss)" and similarly for "int(total_ss)".
I hesitate to apply this change in the master branch, since the error indicates a bug elsewhere. "ss" is not supposed to be None there. I suspect database corruption resulting from parallel loading processes. The root cause is Abe's failure to specify "transaction isolation level serializable" when loading. I would like to fix it, but it would take some effort, and meanwhile, my advice is to have all but one process use --no-load at any given time.
