[guile/scwm] anyone can tell me something about those messages

[P Pareit]

Hey,

I kind of got it working today. Guile was telling me scwm made use of 
deprecated functions, and I started to replace the functions to the ones 
suggested by guile. After replacing scm_sysintern() with scm_define() the 
scwm starts up, windows get drawn but the moment an hook gets called I get 
these kind of errors(?). On some hooks it gets completely wrong, for instance 
it gave me the last errors when I tried resizing an window.

Bad hook: #<variable 4049b1a8 binding: #<hook 1 4049b0a8>>, args = (5)

The <snip>'s where inserted by me for keeping this mail short.
Someone knows what some of the messages mean? I can understand most of them 
but I'm not sure where to look for a solution.

pieter;
