I checked again, and it crashes again.
I'm using R11B4 and some more info on my config:

bash> cat /proc/version
Linux version 2.6.15-28-386 () (gcc version 4.0.3 (Ubuntu
4.0.3-1ubuntu5)) #1 PREEMPT Thu May 10 09:45:43 UTC 2007
bash> erl -version
Erlang (ASYNC_THREADS,HIPE) (BEAM) emulator version 5.5.4
