Crash when asked to download additional torrents

Arch Linux x86_64
QBittorrent 2.5.1

When asked if I wanted to download the torrents in the finished torrent and I press No , qBittorrent crashes with the following report :

"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
