Summary	0003376: PartDesign Boolean produces exception with wrong selection of active Body
Description	If the active Body is selected before launching the Boolean operation tool, an exception message appears: type must be list of 'DocumentObject', not NoneType Exception When clicking OK' the command exits, but an empty Boolean feature is created in the Body tree and set as tip. As a consequence, the Body is broken with an empty tip error. The problem is that both methods for activating a Body (right-click or double-click) leave it selected. There should be a check for invalid selection and a message to warn the end user that the active body should be deselected before launching the tool. Or, activating a Body should automatically deselect it? I don't think there is a good reason to leave it selected.
Steps To Reproduce	Open attached weird-buggy-boolean.fcstd file. Double-click on Body. Click on "Boolean operation with one or more bodies". Error message appears. Click OK. An empty Boolean feature is created in the Body tree.
