I added some notes on the wiki:

  * https://www.kamailio.org/wiki/install/upgrade/4.0.x-to-4.1.0?&#behaviour

The result from database should still be null, just the comparison of $null with $var(...) is done different, which came actually as a fix.

You should test as:

<code>
if($dbr(touser=>[0,0])!=$null) ...
</code>
