hmm, maybe I should fix this?
what I did change, is the time format. it's now iso8601 (which contains no 
whitespaces anymore)

the current tracklog writing (with some small changes - see above...) is a 
good thing, because it's nice to have a continuously updated file, if 
something goes wrong. which is not that easy when using an xml-format or 
something similar.
so the gpx support, which should be in svn right now, is used just for 
exporting the data in memory, not as a continuous tracklog.

yes, we will definitely have this some day...
