could not assemble any primary key columns for mapped table 'sqlite_sequence'

[ba1dr]

Ubuntu 15.10, Python 3.5, Sandman 0.9.8

Trying to open my db.sqlite3 file (created with django, no magic, just some tables with users):

sandmanctl sqlite:////opt/projects/somepath/db.sqlite3

And receive an error:
