Comment 5 for bug 506931

Hi,
I've been getting this crash a few times now, when it crashes when pausing a few torrents at the same time. Version 2.8.4

This is the output when running it from a terminal on amd64

Qt has caught an exception thrown from an event handler. Throwing
exceptions from an event handler is not supported in Qt. You must
reimplement QApplication::notify() and catch all exceptions there.

terminate called after throwing an instance of 'libtorrent::libtorrent_exception'
  what(): invalid torrent handle used
