If a ribbon is minimized, CXTPRibbonControlTab::OnSetPopup calls m_pCOmmandBar->InternalRelease. Then a few lines later it calls CreateTabPopupToolBar. We have code when hide flags are set on a combobox that examines the ribbon bar to find any other combobox the user might have added to the ribbon via customization. That code tests the command bar pointer before looking for any controls in it.

Since the InternalRelease call destroyed the current m_pCommandBar pointer, we are crashing.

I think that after InternalRelease is called, this code should immediately set m_pCommandBar to nullptr.
