Details:

the part of kmlread that tries to parse the placemark text does not handle the
case when the placemark has an id or the following point/linestring/polygon
has an id.

eg the kml syntax for placemark and point are

<Placemark>
Syntax
<Placemark id="ID">
  <!-- inherited from Feature element -->
  <name>...</name>                      <!-- string -->
  <visibility>1</visibility>            <!-- boolean -->
  <open>0</open>                        <!-- boolean -->
  <atom:author>...<atom:author>         <!-- xmlns:atom -->
  <atom:link href=" "/>                <!-- xmlns:atom -->
  <address>...</address>                <!-- string -->
  <xal:AddressDetails>...</xal:AddressDetails>  <!-- xmlns:xal -->
  <phoneNumber>...</phoneNumber>        <!-- string -->
  <Snippet maxLines="2">...</Snippet>   <!-- string -->
  <description>...</description>        <!-- string -->
  <AbstractView>...</AbstractView>      <!-- Camera or LookAt -->
  <TimePrimitive>...</TimePrimitive>
  <styleUrl>...</styleUrl>              <!-- anyURI -->
  <StyleSelector>...</StyleSelector>
  <Region>...</Region>
  <Metadata>...</Metadata>              <!-- deprecated in KML 2.2 -->
  <ExtendedData>...</ExtendedData>      <!-- new in KML 2.2 -->

  <!-- specific to Placemark element -->
  <Geometry>...</Geometry>
</Placemark>


<Point>
Syntax
<Point id="ID">
  <!-- specific to Point -->
  <extrude>0</extrude>                        <!-- boolean -->
  <altitudeMode>clampToGround</altitudeMode>
        <!-- kml:altitudeModeEnum: clampToGround, relativeToGround, or
absolute -->
        <!-- or, substitute gx:altitudeMode: clampToSeaFloor,
relativeToSeaFloor -->
  <coordinates>...</coordinates>              <!-- lon,lat[,alt] -->
</Point>



I have it working by changing line 58 to
 pnam = cell2mat (regexp (xml(max (1, il - 1000):il+7), ...
                               '<Placemark.*?<name>(.+?)</name>.*?<Point',
"tokens")){end};

lines 81 and 116 could be changed similarly.

I have not tested this extensively
