I believe this X crash is due to error messages being printed to the log file after the log file has been closed. This was being done in the signal handler due to a Ubuntu patch. I've corrected the patch to not print these errors, which should eliminate this crash.
However, still whatever problem had caused the X error to begin with is still there, and it is likely that X will still be failing, just without crashing (or perhaps with a different kind of crash). This crash is hiding that information however. So the good news is hopefully this will unhide that information. After updating to version 2:1.7.3.902-1ubuntu7 please re-test your original issue; if it still occurs file a new bug. Hopefully apport will provide better information in this case now. ** Changed in: xorg-server (Ubuntu) Importance: Medium => High ** Changed in: xorg-server (Ubuntu) Status: New => In Progress -- Xorg crashed with SIGSEGV in FatalError() / OsInit() while trying to install linux-headers 2.6.31-9-rt https://bugs.launchpad.net/bugs/504497 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
