Today I switched from GNOME to XFCE 4 and compiz started working. So it is something related with Metacity or some other GNOME app.
Here is what appeared in syslog earlier when I tried to run Compiz on GNOME: inspironjaime2:~# grep compiz /var/log/syslog Oct 26 13:15:55 inspironjaime2 kernel: [104896.009350] compiz.real[16718]: segfault at 7ff8d5672d60 ip 00007ff8d58b52a3 sp 00007fffcb1200d0 error 4 in libglib-2.0.so.0.2200.2[7ff8d5877000+c4000] inspironjaime2:~# Jaime Alberto Silva Colorado Ingeniero Eléctricista Socio / Representante Legal SG Automatización Ltda.
