Olaf,

You were right. The problems were caused by `90-canonscanner.rules` which
then messed up the rest of the rules causing the cascade of errors.

It was an old rule that I had from before the upgrade and that I forgot to
remove... I should have understood for myself that the problem was
there... So I have now solved and there are no more errors.

I apologize for disturbing
Thank you very much

Regards
