Error while downloading OSM data

[uli@…]

Hello,

as requested in the error messages, I am posting the error report
here. I am a GPS and OSM newbie, so I am not sure I'm getting this right ...
However, I'll try. Here's what I did:

I have received a GPX track from a friend for a bike tour in Romania. This
is a quite large track (> 300 km, lots of points). After importing the GPX data,
i used the function "download OSM Data along gpx track" with the settings
"500m" and "5km2". I confirmed the "266 requests necessary" Dialog and the
download started. After some time, the error message popped up, "Unerwarteter Fehler"
but the download continued in the background, or at least it seemed so.
Then, the large error Dialog with the error message text appeared. I could continue
using JOSM after confirming the Dialog.

I tried the same procedure again, and the second time, the whole application
crashed after the small "Unerwarteter Fehler" Message.

Regards,
Uli
