Eclipse unable to find action set of old plug-ins

Question

I was following the instructions from PDE Does Plug-ins to create a few first plug-ins for Eclipse. Everything worked out this far. But when starting the second instance of Eclipse I get the following error information in my console.

General Information:

eclipse.buildId=M20130204-1200
java.version=1.7.0_21
java.vendor=Oracle Corporation
BootLoader constants: OS=win32, ARCH=x86_64, WS=win32, NL=de_DE
Framework arguments:  -product org.eclipse.sdk.ide -refresh
Command-line arguments:  -product org.eclipse.sdk.ide -data C:\Users\Stefan\workspace/../runtime-EclipseApplication -dev file:C:/Users/Stefan/workspace/.metadata/.plugins/org.eclipse.pde.core/Eclipse Application/dev.properties -os win32 -ws win32 -arch x86_64 -consoleLog -clean -refresh

Error Messages:

!ENTRY org.eclipse.ui 4 4 2013-11-17 14:15:39.449
!MESSAGE Unable to find Action Set: HelloWorldPlugin.actionSet

!ENTRY org.eclipse.ui 4 4 2013-11-17 14:15:39.455

!ENTRY org.eclipse.ui 4 4 2013-11-17 14:15:39.456
!MESSAGE Unable to find Action Set: PluginTest.actionSet

When closing the second instance of Eclipse:

!ENTRY org.eclipse.ui 2 2 2013-11-17 14:16:10.359
!MESSAGE Invalid property category path: ValidationPropertiesPage (bundle: org.eclipse.wst.xml.ui, propertyPage: org.eclipse.wst.xml.ui.propertyPage.project.validation)

As you can see I already tried the -clean and -refresh command line parameters and editing the workbench.xmi/.xml , both without success.

I assume these error messages are caused by plug-ins that have previously existed in my workspace, but are no longer existent. Unfortunately these are not listed under 'Installed Plugins' so I cannot remove them this way.

Worth checking out your run configurations for what Plugin's are being looked for:
