IndexError during dephell package list run

[bitphage]

Traceback

Just tried to run the following command:

% dephell package list --traceback
WARNING package not found (package=btrfsutil, url=https://pypi.org/pypi/btrfsutil/json)
ERROR IndexError: tuple index out of range 
Traceback (most recent call last):

    latest=str(releases[0].version),

Not sure where it gets btrfsutil from, I don't have it in dependencies.
