Impossible to start webUI plugin with deluged

[simonbcn]

I start deluged + deluge-web.
I active the webUI plugin (from deluge-web).
I stop deluge-web and deluged.
I start only deluged.
I try to connect to localhost:port but: "Error: Cannot connect to destination".

In log output of deluged:

[INFO    ] 14:06:35 pluginmanagerbase:150 Plugin WebUi enabled..
[INFO    ] 14:06:35 core:97 *** Start Label plugin ***

deluge-web is the alternative standalone program for the webui plugin. you are not supposed to run them together.

I forgot to say that I opened deluge-web to configure deluged and activate the webUI plugin. After this, I stopped both programs and I started deluged only, but: "Error: Cannot connect to destination"

Ok, the problem happens if I activate this from deluge-web: it doesn't create the web_plugin.conf. From deluge-gtk works.
