It seems that the moderator didn't want a message that long to be published,
so I had to delete the full log from the message, but it is still available
from the first message in this thread. You just have to download it and open
it from the disk.

Ok, i saw that the log file is not viewable directly (wrong MIME-type
> specified by server).
> So i copied it as text to the end of this message.
