euca-bundle-vol error diagnostics are unhelpful with invalid --block-device-mapping (2.0.0)

[Antti Haapala]

Without --debug and provided with --block-device-mapping /dev/sda1=ami,/dev/sda2=ephemeral0,/dev/sda3=swap I get after 25 minutes the very unhelpful List index out of range error without any clue as to what its context would be. With --debug I get almost equally unhelpful traceback, with the actual exception type completely suppressed (see below):
