This is fixed in SVN. Thanks a lot for the report!
Note that the hash of the torrent should have been displayed (this is now fixed). The crash on deletion is also fixed.
However, the fact that a 0 size was display is perfectly normal while qBittorrent is getting the torrent's metadata from the swarm. qBittorrent is initially missing this information because the torrent was adding though a magnet link. After a few minutes (provided that the tracker is working), qBittorrent usually gets the metadata from the swarm and updates the missing information (size, content, ...).
