[STUMP] Bug, or something, Stumpwm crashing when creating a new window

[Rohan Nicholls]

Hi everyone,

I am not sure that my last post managed to make it through, because
there has been no reaction.  Basically stumpwm has rendered itself
completely inoperable on my system because any attempt to open a
window, usually by opening a new application makes it crash.  I have
tried to create the problem while sitting in a slime-connect session,
but it bypasses the slime session (probably happening in a different
thread or something) so the best I can do is a backtrace.
I am studying it now, and seeing if I can do anything to fix it, but
my knowledge of the internals of stumpwm are not good.

At a glance it seems that for whatever reason the (current-screen)
value is not being passed to the window creator function thingy.  But
that is just a guess.

I attached the backtrace last time, and the mail seemed to disappear,
so this time I will put the dump inline.

Thanks in advance for any help, as I would love to be able to use
stumpwm again, although this hiatus using other window managers has
reminded me why I love the stump so much.  I will see if I can revive
ratpoison to tide me over.

Rohan
