Deluge does not start after force-rebooting (Xubuntu 13.04)

[Gianfranco Nerdi]

After installing and running Conky Manager, I had to force-reboot using the sudo reboot command while Deluge was still running because the panel had disappeared making the DE almost unusable; however, after rebooting I could no longer start the application. I ran Deluge via terminal, and the message I got was something about the program not being able to acquire a lock; I deleted the two files in the /home/.config/deluge/ipc directory (just as somebody else suggested), and the program worked until I rebooted. Now I can no longer launch the program either using the shortcut I have assigned to it or the panel launcher...neither have I been able to launch it using the applications menu; launching it from the terminal, gives the following message:
Traceback (most recent call last):

However, when I use sudo deluge to launch the application, it does work and start as it normally would.
It also refuses to add a torrent when I double-click on the torrent file or use the context (right click) menu to select the application, even if it's already running.
Is there a way to solve this problem, preferably without having to reinstall the program or use the terminal every time? Because now I have a totally useless panel launcher and cannot launch it from the menu or using the keyboard shortcut.
Update: Now even sudo deluge does not work. Here is what I get when I type the command:

Code: Select all

[ERROR   ] 21:34:05 ipcinterface:156 Deluge restart failed: Couldn't listen on any:/home/arcturus/.config/deluge/ipc/deluge-gtk: Cannot acquire lock.

You have a permission issue with the deluge config, trying deleting the ipc directory

[Gianfranco Nerdi]

I managed to delete the ipc directory by launching Thunar as root; while this does allow Deluge to be launched via terminal again, I still cannot launch it by clicking on the panel launcher or by using the app menu, and right clicking (or double-clicking) on a torrent still does not work.
P.S. Oh, and by the way, I use the 64-bit version of Xubuntu 13.04.

I have no idea what is broken on your system, maybe try reinstalling deluge

rm ~/.config/deluge/ipc/deluge-gtk.lock

Easy peasy. It's the lockfile that prevents multiple instances of the gtk interface that didn't get cleaned up because of a hard reboot.
