I have defined 1 activities category and several activities to remove items from the eclipse platform.  Other than defining the following items in the plugin.xml I do nothing else.  

   <extension
         point="org.eclipse.ui.activities">
      <category
            description="UI Menus, Toolbars, Views, Preferences etc. that have been contributed by dependent eclipse platform plug-ins."
            id="com.itko.lisa.workstation.activities.eclipseUICategory"
            name="Eclipse Platform UI Contributions">
      </category>
      <activity
            description="The External Tools plug-in UI contributions"
            id="com.itko.lisa.workstation.activities.externalTools"
            name="External Tools">
      </activity>
      <categoryActivityBinding
            activityId="com.itko.lisa.workstation.activities.externalTools"
            categoryId="com.itko.lisa.workstation.activities.eclipseUICategory">
      </categoryActivityBinding>
      <activityPatternBinding
            activityId="com.itko.lisa.workstation.activities.externalTools"
            pattern="org\.eclipse(\.)ui\.externaltools/.*">
      </activityPatternBinding>
      <activity
            id="com.itko.lisa.workstation.activities.search"
            name="Search">
      </activity>
      <categoryActivityBinding
            activityId="com.itko.lisa.workstation.activities.search"
            categoryId="com.itko.lisa.workstation.activities.eclipseUICategory">
      </categoryActivityBinding>
      <activityPatternBinding
            activityId="com.itko.lisa.workstation.activities.search"
            pattern="org\.eclipse\.search\.ui\.(.*)?">
      </activityPatternBinding>
      <activityPatternBinding
            activityId="com.itko.lisa.workstation.activities.search"
            pattern="org\.eclipse\.search/.*\.search\..*">
      </activityPatternBinding>
      <activity
            id="com.itko.lisa.workstation.activities.navigate"
            name="Navigate">
      </activity>
      <categoryActivityBinding
            activityId="com.itko.lisa.workstation.activities.navigate"
            categoryId="com.itko.lisa.workstation.activities.eclipseUICategory">
      </categoryActivityBinding>
      <activityPatternBinding
            activityId="com.itko.lisa.workstation.activities.navigate"
            pattern="org\.eclipse\.ui\.navigate\..*">
      </activityPatternBinding>
      <activityPatternBinding
            activityId="com.itko.lisa.workstation.activities.navigate"
            isEqualityPattern="true"
            pattern="org.eclipse.ui.edit.text.gotoLastEditPosition">
      </activityPatternBinding>
      <activityPatternBinding
            activityId="com.itko.lisa.workstation.activities.navigate"
            isEqualityPattern="true"
            pattern="org.eclipse.ui.views/org.eclipse.ui.views.properties.NewPropertySheetCommand">
      </activityPatternBinding>
      <activity
            id="com.itko.lisa.workstation.activities.fileDelimiters"
            name="File Delimiters">
      </activity>
      <activityPatternBinding
            activityId="com.itko.lisa.workstation.activities.fileDelimiters"
            pattern="org\.eclipse\.ui\.edit\.text\.delimiter\..*">
      </activityPatternBinding>
      <categoryActivityBinding
            activityId="com.itko.lisa.workstation.activities.fileDelimiters"
            categoryId="com.itko.lisa.workstation.activities.eclipseUICategory">
      </categoryActivityBinding>
   </extension>


However, the platform keeps throwing the following exception:

Note, I'm using 3.7M3 with a target platform of 3.6.1.
