umbrello saves the structure of the UML-Modell into xmi files using the following xml part 

<XMI.extensions xmi.extender="umbrello" >
  <docsettings viewid="zP4dmW2l6Cmc" uniqueid="TjgSlRabpHvx" documentation="" />
  <listview>
   <listitem open="1" type="800" label="Views" >
    <listitem open="1" type="801" id="Logical View" >
     <listitem open="0" type="807" id="zP4dmW2l6Cmc" label="Klassendiagramm" />
     <listitem open="1" type="813" id="TjgSlRabpHvx" />
     <listitem open="0" type="830" id="Datatypes" >
      <listitem open="1" type="829" id="BQkijZbOKvW1" />

    </listitem>
    <listitem open="1" type="802" id="Use Case View" />
    <listitem open="1" type="821" id="Component View" />

The problem is that the label attribute of the following entry is writeen language specific 

   <listitem open="1" type="800" label="Views " >

With english language there is written 
<listitem open="1" type="800" label="Views" >

with german language
 <listitem open="1" type="800" label="Ansichten" >



other similar entries uses a language independent id attribute for example 

    <listitem open="1" type="801" id="Logicaal View" >

so i guess a bug fix would be to replace the lable attribute with a id="Views" attribute.
