[STUMP] Stumpwm freezes with xscreensaver

[Dmitri Minaev]

Hello,

For a couple of months I used Stumpwm under Ubuntu. Sometimes it
crashed (especially when I launched 'djview') and froze (especially
after unlocking the xscreensaver). It was built using standard Ubuntu
SBCL, version 1.0.6 with sb-threads. So, I decided to recompile SBCL
without threads and to rebuild Stumpwm. So I did. Now, SBCL is 1.0.13,
but, to my disappointment, Stumpwm still locks up after I enter the
password in xscreensaver. I still can switch to another virtual
terminal, so I am not sure if this is a 'real' freeze.

If I launch Stumpwm from sbcl, I don't see any especially terrifying
messages and sbcl doesn't start the debugger when I switch to the sbcl
terminal. What do you think I should upgrade next time? :) Thank you.

The last lines of the Stumpwm output and the backtrace is below:
