Deluge over X

[nicexe]

I was testing Deluge over an X session.
The first run configuration appeared and finally I was downloading a torrent file.
I paused the downloading file and after a while I terminated the program.
now every time I try to launch deluge I get this error messages:

Code: Select all

[nicexe@server5085 bin]$ deluge

    st = os.stat(path)

What's wrong? How can I fix it?
