[STUMP] define-frame-preference

[Luis Octavio Silva]

Dear stumpwm comunity,

I apologize for asking a question not related with the development of
the marvellous stumpwm. It seems that, without help from you, I am
unable to solve a problem I have when trying to configure the wm. I
have the git version 2013-01-05. The following is in my .stumpwmrc
file:

(define-frame-preference "devel"
  (0 t t :restore "/home/silva/.stumpwm.d/devel" :title "...pdf")
  (1 t t :title "emacs")
)

This is what I have in the devel file:

#S(GDUMP
   :NUMBER 2
   :NAME "devel"
   :TREE ((#S(FDUMP
              :NUMBER 0
              :X 0
              :Y 0
              :WIDTH 960
              :HEIGHT 1080
              :WINDOWS nil
              :CURRENT nil)
           #S(FDUMP
              :NUMBER 1
              :X 960
              :Y 0
              :WIDTH 960
              :HEIGHT 1080
              :WINDOWS nil
              :CURRENT nil)))
   :CURRENT 0)

I understand from the documentation that, if I launch the xpdf viewer
while being working on emacs, the frame will be splitted in two (one
with emacs and the other with xpdf). Unfortunately, I always get one
window on top of the other without any splitting and the message:

Can't restore group "devel" with #<PATHNAME (with no namestring)
                                       :HOST #<SB-IMPL::UNIX-HOST
                                                       {100001B503}>
                                       :DEVICE NIL
                                       :DIRECTORY (:ABSOLUTE
                                                   "home"
                                                   "silva"
                                                   ".stumpwm.d")
                                       :NAME  "/home/silva/.stumpwm.d/devel"
                                       :TYPE NIL
                                       :VERSION NIL>

Any help will be greatly appreciated.
