[]So cat is not 'num' if "Googlebotfriendly" is activated in the Board prefs?
(Or do I have a problem in the database?) [/]
Well that's a problem of ubbthreads an not a problem of this modification. The function that translates the search engine friendly urls back into variables is a very simple one.
It takes the url and takes all "subdirectories" as key/pair values.
So long story short: If your url is invalid, the translation into variables will fail which causes a security alert.
Invalid url: /Cat/0/Number/35279/page/vc/1
Valid url: /Cat/0/Number/35279/page/0/vc/1

And what is to do with "unknown formats?

See the readme.txt for details, but basically you can add them in ubbt.inc.php with:
$validate->addKnownParam('U_Language','text');
$validate->addKnownParam('U_AcceptPriv','text');
$validate->addKnownParam('U_TimeFormat','text');
