I have to admit, that I recently changed from WinXP to Ubuntu Linux and my knowledge of Linux is not very advanced, so I don't know how to install from "svn trunk". I always wait for published .deb Files and then install Deluge.
do this:
sudo apt-get install g++ python-all-dev python-all version python-dbus python-gtk2 version python-xdg python-support libboost-dev libboost-thread-dev libboost-date-time-dev libboost-filesystem-dev libboost-serialization-dev libssl-dev zlib1g-dev subversion; sudo apt-get --purge remove deluge-torrent; rm -rf ~/.config/deluge; svn co http://deluge-torrent.org/svn/trunk deluge; cd deluge; make; make install; deluge
After some testing I realized that the "Segmentation fault (core dumped)"-crash only occurs with a specific torrent, independently of specific files selected or not. So the problem lies within this .torrent file.
