1. Install EGit
2. Open Resource perspective.
3. Note the error message in the log:

"Referenced part does not exist yet: org.eclipse.jdt.ui.PackageExplorer."

The bug also causes Platform/UI JUnit test failure in IWorkbenchPageTest#testOpenAndHideEditor11().

The problem is in the following code in the plugin.xml of the "org.eclipse.egit.ui" bundle:

   <extension
         point="org.eclipse.ui.perspectiveExtensions">
      <perspectiveExtension
            targetID="*">
         <view
               id="org.eclipse.egit.ui.RepositoriesView"
               minimized="false"
               ratio="0.6"
               relationship="bottom"
               relative="org.eclipse.jdt.ui.PackageExplorer"
               visible="false">
         </view>
      </perspectiveExtension>
   </extension>

Note that this extension applies to all perspectives ("*") and it wants to be positioned relative to the PackageExplorer.

Well, not all perspectives have PackageExplorer view. For those that do not, this extension creates a error.

I'd highly suggest removing this extension.
