Can't open Themes, Themosis throws exception

[pandabrand]

When I try to activate the Themosis theme I get this exception:
#0 /Users/pandabrand/Sites/themosis/wp-content/plugins/themosis/src/Themosis/Core/Start.php(205): Themosis\Error\Error::native(512, 'An unexpected e...', '/Users/pandabra...', 407)
