eek, that's formatted pretty badly.. maybe you could add the traceback as an attachment instead?

Is it possible that you have a node that was initialized before the switch-to-zbase32 change that occurred on july-24, but is now running with new code?

The dirnode URI format changed (and testnet was flushed), so you need to at least remove the global_root.uri and my_vdrive.uri files from it. You may want to delete the whole node and create a brand new one.

If you make a new node and look at those files, check to see if the URIs look different between your old one and the new one. The old ones would have lots of trailing === marks, the new ones should have no equal marks.

If we can confirm that this is the problem, could you close this ticket?

thanks,
-Brian

Also changeset:dbcabc114234cfe5 made it so that this kind of incompatibility will be handled nicely explicitly from now on. arch: please close this ticket if you agree that the issue is fixed.
