Unfortunately this is not a Deluge issue and based on the message it's likely related to boost, so you could try reinstalling boost packages.

[Joe Sweeney (joesweeney413)]

i've tried that several times, and a few different versions, still runs for about 10-15 seconds and closes itself out.

[Cas (calumlind)]

I see that you are using libtorrent 0.16.3, I wonder if installing the latest version might help.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Hawk (jedihawk)]

Same behavior on my system. Runs for less than a minute, then crashes.

$ uname -a
Linux mysystem 3.5.0-22-generic #34-Ubuntu SMP Tue Jan 8 21:47:00 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

$ /usr/local/bin/deluged -d -L debug
...

  what(): std::bad_cast

(or)

$ deluged --version
deluged: 1.3.5
libtorrent: 0.16.3.0

$ deluged -d -L debug
...
terminate called after throwing an instance of 'std::bad_cast'
  what(): std::bad_cast

How to fix?

[Cas (calumlind)]

As I said before it is a libtorrent or boost issue so if you could test with latest version of libtorrent along with deluge 1.3-stable code that would be helpful.

Also have you attempted to get a gdb backtrace?

[Nathan Willis (n8)]

I can confirm that this happens on 12.04 LTS as well. Or rather, it just struck today, after having been running without incident for ages. Libtorrent and boost both up to date. Other ideas, perhaps?

[Russell O'Connor (launchpad-roconnor)]

I was able to work around this issue by disabling all my Proxies (Socksv4). So it seems that the Socks proxies may have something to do with this issue.

[Expired for deluge (Ubuntu) because there has been no activity for 60 days.]

[Aaron Hopkins (c-launchpad-x)]

I ran into this issue, too, also with SOCKS proxies with deluged-1.3.6-0ubuntu2 on Ubuntu 13.04. The settings for all four proxies in ~/.config/deluge/core.conf that cause deluged to die with the abort due to std::bad_cast are:

      "username": "",
      "password": "",
      "type": 1,
      "port": 3180,
      "hostname": "10.1.2.3"

 I was able to work around the issue. I changed the configuration for all four proxies to something like the following, which don't seem to lead the same crashes:

      "username": "none",
      "password": "none",
      "type": 2,
      "port": 3180,
      "hostname": "10.1.2.3"

And I was able to capture a backtrace from GDB:

I've been having a similar issue. I do not remember exactly when this started, but it appears to have been occurring fairly frequently for a couple of months now.

[Michael Tinsay (tinsami1)]

For me, deluge-gtk on 12.04 eventually crashes when I have encryption Enabled or Forced (see http://forum.deluge-torrent.org/viewtopic.php?f=7&t=41843). Setting it to Disabled eliminates the crashes.

[Cas (calumlind)]

It might be worth testing with latest versions of 0.16. There is a PPA that contains up to date versions of 0.16 here: https://launchpad.net/~surfernsk/+archive/ubuntu/internet-software

If you are using 12.04 then it is highly recommended to upgrade to 0.16 libtorrent but that is due to a different issue to this one.
