As far as I can tell, this breakage was introduced in chage 33398.
The comment for that change says,

   Restores the workflow start and stop actions to the item workflow UI.

This may work for a Workflow attached to an item.  In the case of the
Workflows tab, we are dealing with WorkflowTemplate instances - not
Workflow instances.  The WorkflowTemplate class is a subclass of
Workflow that overrides the getProcessState method (as well as a bunch
of other methods) like so:

    public int getProcessState() {
        throw new UnsupportedOperationException();
    }


In change 33398, the following piece of code was added to
//cms/dev/src/com/arsdigita/cms/ui/workflow/BaseWorkflowItemPane.java#8

>  public final boolean isVisible(final PageState state) {
>      final Workflow workflow = m_workflow.getWorkflow(state);
> 
>      return workflow.getProcessState() == Workflow.STOPPED;
>  }


This works as long as the "workflow" is an instance of Workflow.  If
it is an instance of the subclass WorkflowTemplate, the method
obviously breaks.
