    mconvert: enable recursive scheme lookup and fix a crasher
    
    The recursive scheme lookup is needed to scan the whole settings path. The crash
    would happen in the case of a misconfiguration (e.g. building gconf from source
    and running uninstalled while the configure settings don't match the one used to
    create the installed package).
