the condition is in question:

<condition class="CustomXQueryBodyChecker" negate="false">
<param name="xquery" value="(count(//*[local-name()='SomeRequest' and namespace-uri()='urn:company:xy:xxxx:yyyy:v1'][1])=1)"/>
</condition>

Not bug, expected behavior, as the request was malformed and condition checker cannot evaluate it. Wilma response is the right expected result.

Enhancement possibility: give more info on the problematic request, like the ID of the message.
