I have tried some more and narrowed the problem down i think.
In the "pm_messagelistbit_preview" template is the following code:

<li class="blockrow pmbit" id="pm_{vb:raw pm.pmid}">
	<div class="datetime">
		<label for="pm_imod_checkbox_{vb:raw pmid}">{vb:raw pm.senddate} <span class="time">{vb:raw pm.sendtime}</span> <vb:if condition="$show['pmcheckbox']"><input type="checkbox" name="pm[{vb:raw pmid}]" id="pm_imod_checkbox_{vb:raw pmid}" value="{vb:raw groupid}" /></vb:if></label>
	</div>
	<img src="{vb:stylevar imgdir_statusicon}/pm_{vb:raw pm.statusicon}.png" class="threadicon" alt="" />
	<vb:if condition="$show['pmicon']">
		<img src="{vb:raw pm.iconpath}" class="posticon" alt="{vb:raw pm.icontitle}" />
	</vb:if>
	<vb:if condition="!$show['unread']">
		
		 {vb:raw userbit} <a href="private.php?{vb:raw session.sessionurl}do=showpm&amp;pmid={vb:raw pm.pmid}" class="title">{vb:raw pm.title}</a>
                 
		 <fieldset style="padding-left:10px;width:80%;">{vb:raw preview}</fieldset>
	<vb:else />
		<span class="unread">
		{vb:raw userbit} <a href="private.php?{vb:raw session.sessionurl}do=showpm&amp;pmid={vb:raw pm.pmid}" class="title">{vb:raw pm.title}</a>
		</span>	
		 <fieldset style="padding-left:10px;width:80%;">{vb:raw preview}</fieldset>
		
	</vb:if>
	<hr class="none" />
</li>

If I remove the red marked code, the word "Array" is gone. However, there is also no username from who you got the PM.

Is there an other code for "{vb:raw userbit}"?
