Comment:

 other issue in this area of the WP code. unless I'm mistaking, activating
 a plugin that is already active will generate an error. to fix, replace
 this line in activate_plugin():

 @include(ABSPATH . PLUGINDIR . '/' . $plugin); // error: cannot redeclare
 function/class

 with:

 @include_once(ABSPATH . PLUGINDIR . '/' . $plugin); // no error

 and/or, check if the plugin isn't active already before going through the
 entire procedure.
