I'm suffering from this issue as well. (running 32-bit Ubuntu 9.10) This far I've disabled the screen locking through gconf as both my own user and as root, and I also tried disabling it in /etc/default/acpi-support with no effect.
This problem seems to only occur when suspending using the Indicator-Applet-Session applet, suspending with the Shut Down-applet or by closing the laptop lid works correctly.
