Very comparable failure on my machine - SCIM seems to be not very functional. It's initialization and "code page" changing code seems to trigger this off.

Charles or charlie, could either of you describe in more detail how this bug gets triggered? You mention something about it relating to SCIM?

There are two other recent bug reports about crashes in atieventsd. While their backtraces differ, I wonder if they might be related: bug 193559 and bug 194249.

For me it occurred after I restarted once an update was complete. Other than that I don't have much knowledge of what caused it.

There were a number of updates installed (probably 25 or more) that were
installed. I have been updating 8.04 periodically (sometimes daily,
sometimes more like weekly, and this was after several days of not
updating).

There were only two obvious things I noticed: the large number of
updates, and the fact that I got an error message and a hang when
shutting down that referred to the SCIM initialization. I do not know
if this was the initial install of SCIM or if previous installs and
updates just did not generate any errors so I had not noticed it.

I was able to get past the problem by reinstalling 8.04 from the CD, and
then I used the Synaptic Package Manager to update all packages,
unchecked all the updates that referred to SCIM, and rebooted (as
requested). I then updated the SCIM packages and all worked well.

As of Intrepid (8.10), we have a dedicated package 'fglrx-installer' for fglrx bugs, which now includes a process for upstreaming bugs to AMD.

  http://bugs.launchpad.net/ubuntu/+source/fglrx-installer

To transition your bug into the new fglrx-package, we need your help. Please do the following:

 a. Verify the bug occurs in Intrepid.
     (Intrepid ISOs: http://cdimage.ubuntu.com)
 b. If you haven't already, please include in the bug:
     * Your /var/log/Xorg.0.log
     * The output of `lspci -vvnn`
     * Steps to reproduce the issue
 c. Click 'Also affects distribution'
 d. Set 'Source Package Name' to 'fglrx-installer'
 e. Click Continue

Thank you. This will assist us in reviewing and upstreaming your fglrx bug, as appropriate.

[We'll expire the fglrx bugs in l-r-m-* in a month or so.]

I've let the system not install any updates for a couple of weeks, then blasted them all at once (the only thing that seems to trigger this) and neither an update of 86 or so files nor the version update to Intrepid (1600 or so files) resulted in any such failures, so it may be fixed.

Great.
