How about just leave building from source for now and only install the official precise repository packages for deluge and libtorrent to see if those will work.

Both are the same. Is the official one in /usr/bin?

$ /usr/bin/deluged -v
deluged: 1.3.5
Segmentation fault (core dumped)

$ /usr/local/bin/deluged -v
deluged: 1.3.5-dev
Segmentation fault (core dumped)

A segfault is usually a libtorrent issue so what version of libtorrent and do you have a backtrace?

There are bunch of them.

Please remove/purge all libtorrent packages and any remaining files. Then install libtorrent-rasterbar6 and python-libtorrent from the Precise apt repository.

There are two libtorrent libraries one is for rtorrent and the other is libtorrent-rasterbar which is used by Deluge and other torrent clients.

That eventually helped!
Obviosly it was some broken libtorrent libs.
I had to wipe all libtorrent* files manually, then installed packages as usual and it worked.

Thanks a lot for helping!
