We scanned PyDev (3.7.1) and found that one (and only one) file is license under GPLv3 (\plugins\org.python.pydev.core\src\org\python\pydev\core\uiutils\UIUtils.java). There are applicable exceptions, but the text related to the exceptions are not included with the sources.
On the www.aptana.com web site, there is a text related to these exceptions (clue?) http://www.aptana.com/legal/aplgplex. The text is quite obscure. But at the end, there is the following:
"However, in addition to the other notice obligations of this License, all copies of any covered work conveyed by you must include on each user interface screen and in the Appropriate Legal Notices the following text: "Powered by Aptana". On user interface screens, this text must be visibly and clearly displayed in the title bar, status bar, or otherwise directly in the view that is in focus."
This means that user interface screens of Eclipse that includes the PyDev plugin, should display "Powered by Aptana", which is not the case today.
What can we do?

That's an error in the header. PyDev should all be EPL. I'll fix it.
