I too was experiencing this issue on Ubuntu 10.10 x86_64 running Deluge 1.3.1.
After a few google searches, I discovered that my issue was related to the "Open Folder" option in the torrent context menu. Full details here: http://dev.deluge-torrent.org/ticket/1396
I've stopped using that option 2 weeks ago and I haven't experienced this issue since.
