The versions of the programs in question here date from October 2009.
http://www.lacie.com/support/drivers/driver.htm?id=10081The versions mentioned in 2006 are the ones I used in mga 2 and before - without any segfault problem.
lightscribe-1.4.142.1-linux-2.6-intel.rpm
lightScribeSimpleLabeler-1.4.128.1-linux-2.6-intel.rpm
The on-line posts (2006) I can find refer to the lightscribe System Software program (4L) segfaulting. However that program seems to start up OK here without segfault. The problem here is with the SimpleLabeler program (which depends on the System Software program).
In the 2006 posts, as here, the strace indication is as you point out related to the attempt to handshake with the disk.
If all else fails, I can boot into kororaa (fedora) to burn a label.
I do not have alternative hardware to try.
UPDATE:
http://www.lightscribe.com/downloadSection/linux/index.aspxHave just installed and run successfully in cauldron - SimpleLabeler.
Date modified on the executable is May 19, 2010
Have reinstalled same program in mga 3. Still no joy.
From the look of the UI this program is unchanged from the original in 2006.
EDIT:
Reinstalled system software, 4L, and SimpleLabeler in mageia3. Only 4L works here, not SimpleLabeler.
Both 4L (LaCie) and SimpleLabeler (lightscribe) work in cauldron.
Installations are identical.
