After further research I believe I have found the problem. In
org.eclipse.datatools.connectivity.ui.dse you have the following:
<extension
point="org.eclipse.ui.views.properties.tabbed.propertyContributor">
<propertyContributor
contributorId="org.eclipse.datatools.connectivity.DataSourceExplorerNavigator"
labelProvider="org.eclipse.ui.internal.navigator.resources.workbench.TabbedPropertySheetTitleProvider">
<propertyCategory category="general"/>
<propertyCategory category="core"/>
<propertyCategory category="appearance"/>
<propertyCategory category="advanced"/>
</propertyContributor>
</extension>
This problem is only triggered if the properties view is a tabbed
properties view.
