It would help to have some more details:

• A copy of the smart playlist xml file
  
• What db - SQLite, MySQL (and version) or related

op edited while replying, oh well...

Why do problems disappear the moment you finally decide to post about it?

In the end I discovered that changing the sorting from ascending to descending solved it. This is strange because it shouldn't be sorted to begin with.

Code:

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<smartplaylist type="songs">
    <name>Sans shite</name>
    <match>all</match>
    </rule>
    <rule field="genre" operator="doesnotcontain">
        <value>Klassiek</value>
    </rule>
    <rule field="genre" operator="doesnotcontain">
        <value>Humor</value>
    </rule>
    <rule field="genre" operator="doesnotcontain">
        <value>Comedy</value>
    </rule>
    <rule field="album" operator="doesnotcontain">
        <value>Ultra-Lounge</value>
    </rule>
    <rule field="genre" operator="isnot">
        <value>Classical</value>
    </rule>
    <rule field="album" operator="doesnotcontain">
        <value>Vakantie</value>
    </rule>
    <rule field="album" operator="isnot">
        <value>Amazone</value>
    </rule>
    <rule field="genre" operator="doesnotcontain">
        <value>Easy Listening</value>
    </rule>
    <limit>250</limit>
    <order direction="descending">random</order>
</smartplaylist>

For me, this workaround fixes the problem but maybe its designed to work this way.
