according to :
http://api.kde.org/4.x-api/kdeedu-apido ... Track.html

"GeoDataTrack implements the Track tag defined in Google's extension of the Open Geospatial Consortium standard KML 2.2 at http://code.google.com/apis/kml/documen ... ml#gxtrack ."

I tried to use a simle kml file from that link :
<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2"
xmlns:gx="http://www.google.com/kml/ext/2.2">

</gx:Track>
</Placemark>
</Folder>
</kml>

and when I try to add this map threw "MarbleModel::addGeoDataFile(const QString& filename)" I get an assertion failure.
I believe it happens because gx:Track and gx:coord are nor supported.
Is it true?

I tried the file with both Marble from KDE 4.10 (Marble 1.5) and latest master (to be Marble 1.6) and both load and display the track fine. Which Marble version are you using? What does the assertion say / where is it triggered exactly?
