  <navigation:NavigationBar>
    <navigation:NavigationPane>
      <navigation:NavigationPane.Header>
        <ComboBox/>
      </navigation:NavigationPane.Header>
    </navigation:NavigationPane>
  </navigation:NavigationBar>
The above code will display the ComboBox ToString()'ed as though there is a default HeaderTemplate set. This is not standard WPF behavior. Goofily the following works:
      
  <navigation:NavigationBar>
    <navigation:NavigationPane>
      <navigation:NavigationPane.HeaderTemplate>
        <DataTemplate>
          <ComboBox/>
        </DataTemplate>
      </navigation:NavigationPane.HeaderTemplate>
      <navigation:NavigationPane.Header>
        <ComboBox/>
      </navigation:NavigationPane.Header>
    </navigation:NavigationPane>
  </navigation:NavigationBar>

Hi Owen,

First please note that this forum is meant for issues/questions pertaining to Ribbon for WPF.

To answer your question, the NavigationPane uses a default HeaderTemplate that properly presents string values (using bold, text trimming, and padding), since that handles most cases.

If you set HeaderTemplate to null, then the Navigation pane would work as you are expecting. Something like this:
<navigation:NavigationBar>
    <navigation:NavigationPane HeaderTemplate="{x:Null}">
        <navigation:NavigationPane.Header>
            <ComboBox />
        </navigation:NavigationPane.Header>
    </navigation:NavigationPane>
</navigation:NavigationBar>
