This stops firefox from running in a default rawhide install.

Are you running flash? This seemed to only happen after I got flashplugin for the adobe repos and restarted.

Just to note that my problems were reproducible even on KVM virtual machine (with i586) which has no traces of anything related to flash (no flash-plugin, no libflash* anywhere).
