Copy paste from Emacs to Claws-mail

[Jakub Jankiewicz <jcubic@jcubic.pl>]

I'm not sure if this is bug in Emacs or bug in Claws-mail but it don't work
when I copy/paste (yank) text from Emacs to Mail creator. I'm using GTK+ and
Fedora XFce. And have this error:

Debugger entered--Lisp error: (error "Selection owner couldn't converted"
MULTIPLE)

Also I was not able to copy that string from Emacs and I've needed to write
it by hand (so it may be not exactly the same).

I have this setup in my .emacs:

(setq x-select-enable-clipboard t)
(setq mouse-drag-copy-region t)
(setq x-select-enable-clipboard-manager nil)
(setq interprogram-paste-function 'x-cut-buffer-or-selection-value)

Because of this I need to keep Mousepad text editor as proxy to paste text
from GNU Emacs into an email.
