#204 3.1 crashes on exit sometimes

Sometimes when im downloading and close the window, ABC
crashes. Then I find out the file being downloaded is
lost! (This happens at least with multi-file torrents=-
As a workaround i have to press stop and then close.
Then it crashes but at least the downloaded file is
still found. As an additional information, i download
my files in drives different than C:.

Here's the log (there have been various crashes so i
post them all):
