Package: transmission-qt
Version: 3.00-1
Severity: normal
I have a reproducible, complete crash when adding a torrent with
transmission-qt on a remote transmission-daemon server:

Strangely, the torrent does get added and I can restart
transmission-qt to see it correctly, so I am not marking this as RC,
but it does feel pretty bad.
