We load the application UI state (toolbar positions) with this code:
WINDOWPLACEMENT dataFrameWP;
CWinApp *app = AfxGetApp();
CExtControlBar::ProfileBarStateLoad( this, app->m_pszRegistryKey, app->m_pszProfileName, app->m_pszProfileName, &m_dataFrameWP);
This fatally crashes if there has been a change to the application which has added or removed toolbars or windows. Deleteing the registry keys fixes the crash. There does not appear to be a way to validate state before loading which might prevent this crash.
How do we validate state so that we can skip the load if it would otherwise cause a crash? A try / catch block around the ProfileBarStateLoad call does not prevent a crash.
Thanks in advance!

From around version 2.51, there has been a new parameter added to ProfileBarStateLoad, called bEnableThrowExceptions. By default, this is false, but if you call ProfileBarStateLoad with bEnableThrowExceptions set to true, a try/catch block will prevent the crash. Same goes for CExtCmdManager::SerializeState.
