[Gpsbabel-misc] Wintec WBT-201 incorrect KML generated

[<ax...@mu...>]

Recently I purchased a Wintec WBT-201 due to the Linux support for 
Wintec devices in the past and the upcoming support for the WBT-201.
I built gpsbabel from CVS without problems. Communication with the 
WBT-201 seems to work using:

gpsbabel -t -w -i wbt -f /dev/ttyUSB1 -o kml -F out.kml

However the generated KML file contains incorrect data: Only the first 
and the last waypoint/placemark has correct data, all others are incorrect:

First placemark:

      <Placemark>
        <name>WP0001</name>
        <TimeStamp><when>2007-06-12T19:23:46Z</when></TimeStamp>
        <styleUrl>#waypoint</styleUrl>
        <Point>
          <coordinates>8.982297,50.293437,132.000000</coordinates>
        </Point>
      </Placemark>

Placemark somewhere in the middle:

      <Placemark>
        <name>WP0206</name>
        <TimeStamp><when>1928-02-25T01:35:47Z</when></TimeStamp>
        <styleUrl>#waypoint</styleUrl>
        <Point>
          <coordinates>-0.000000,-0.000000,-1.000000</coordinates>
        </Point>
      </Placemark>

Last placemark:

      <Placemark>
        <name>WP0241</name>
        <TimeStamp><when>2007-06-13T04:05:41Z</when></TimeStamp>
        <styleUrl>#waypoint</styleUrl>
        <Point>
          <coordinates>8.980277,50.292103,113.000000</coordinates>
        </Point>
      </Placemark>


For waypoints the situation is similar.

Besides the CVS version I also tried the compiled version available from 
http://hexten.net/downloads/gpsbabel-1.3.4beta-wbt201-feisty-i386.tar.gz 
with the same result.

The WBT-201 works properly using the bundled software for Windows.

Any ideas?
