    When I open the samples view, I try to move it into the same group as the App Explorer. When I start dragging the tab, it just disappears, and throws an NPE: java.lang.NullPointerException at org.eclipse.ui.internal.FastViewPane.hideView(FastViewPane.java:582) at org.eclipse.ui.internal.Perspective.hideFastView(Perspective.java:571) at org.eclipse.ui.internal.Perspective.setActiveFastView(Perspective.java:1933) at org.eclipse.ui.internal.Perspective.setActiveFastView(Perspective.java:1952) at org.eclipse.ui.internal.Perspective.toggleFastView(Perspective.java:2365) at org.eclipse.ui.internal.WorkbenchPage.toggleFastView(WorkbenchPage.java:3873) at org.eclipse.ui.internal.WorkbenchPage.hideFastView(WorkbenchPage.java:3861) at org.eclipse.ui.internal.FastViewPane$2.dragStart(FastViewPane.java:156) at org.eclipse.ui.internal.FastViewPane$2.dragStart(FastViewPane.java:136) at org.eclipse.ui.internal.presentations.util.TabbedStackPresentation$1.handleEvent(TabbedStackPresentation.java:118) at org.eclipse.ui.internal.presentations.util.AbstractTabFolder.fireEvent(AbstractTabFolder.java:269) at org.eclipse.ui.internal.presentations.util.AbstractTabFolder.fireEvent(AbstractTabFolder.java:282) at org.eclipse.ui.internal.presentations.util.AbstractTabFolder.handleDragStarted(AbstractTabFolder.java:366) at org.eclipse.ui.internal.presentations.util.AbstractTabFolder$2.handleEvent(AbstractTabFolder.java:67) at org.eclipse.ui.presentations.PresentationUtil.handleMouseMove(PresentationUtil.java:110) at org.eclipse.ui.presentations.PresentationUtil.access$4(PresentationUtil.java:95) at org.eclipse.ui.presentations.PresentationUtil$2.handleEvent(PresentationUtil.java:63) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Display.sendEvent(Display.java:3776) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1367) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1390) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1375) at org.eclipse.swt.widgets.Widget.notifyListeners(Widget.java:1187) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:3622) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3277) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2640) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2604) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2438) at org.eclipse.ui.internal.Workbench$7.run(Workbench.java:671) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:664) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at com.aptana.rcp.IDEApplication.start(IDEApplication.java:125) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:196) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:369) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:592) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:619) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:574) at org.eclipse.equinox.launcher.Main.run(Main.java:1407) at org.eclipse.equinox.launcher.Main.main(Main.java:1383)
