Bug Description
Binary package hint: xorg
We're attempting to install from a Natty daily image, through the network and using a preseed file.
The installation starts normally and goes up to a certain point, but then the installer exits and we're dropped to the LiveCD graphical environment. Sometimes a "system program failed" message appears.
syslog shows a sefgault on Xorg, which is probably what's causing the installer to die.
This particular trace was produced on a Dell Vostro 3400, though the problem has been observed on other machines as well.
The installation worked before: the last known good image we tried was from 20110112. The first one where we observed this problem was 20110119. We also tried 20110120, 20110121 and the latest one today (2011-01-27).
