[grsec] Firefox

When I load up firefox 1.0, I get a message:

(firefox-bin:12534): Gdk-WARNING **: shmat failed: error 13 (Permission
denied)
*** loading the extensions datasource

It is a grsec2.1.6 2.6.11.12 kernel.

Could this shared memory issue be due to PaX settings:

CONFIG_PAX=y
CONFIG_PAX_SOFTMODE=y
CONFIG_PAX_PT_PAX_FLAGS=y
CONFIG_PAX_NO_ACL_FLAGS=y
CONFIG_PAX_ASLR=y
CONFIG_PAX_RANDKSTACK=y
CONFIG_PAX_RANDUSTACK=y
CONFIG_PAX_RANDMMAP=y
CONFIG_PAX_NOVSYSCALL=y

as the grsec is not enabled.

TIA

John
