After updating to the latest dev rev (2013-May-08) i keep getting this notice.

Notice: Trying to get property of non-object in project_plugin_argument_default_project_type->get_argument() (line 17 of /pathtodrupal/sites/all/modules/project/views/plugins/project_plugin_argument_default_project_type.inc).

Any ideas why this is happening and is anyone else seeing this issue?
