New facts I find. 1. kernel-2.6.10-1.737_FC3 is OK. 2. Editing /etc/udev/permissions.d/50-udev.permissions dri/*:root:root:0660 ---> dri/*:root:root:0666 In this case, kernel-2.6.10-1.1076_FC4 is OK. 3. In kernel-2.6.10-1.737_FC3, even though not editing 50-udev.permissions, the sypmtom does not occure. I don't know which has a problem kernel or OpenOffice.
when you get the segmentation fault, is there a kernel panic in the output of 'dmesg' ? 660 is correct permissions for this devnode, as otherwise it would be a security hole.
No, there is not a kernel panic.
