[Bug 1047996] Re: USB startup disk creator crashes compiz

[ethanay]

Dell XPS m1330 w/Intel GM965 graphics on Ubuntu 32-bit w/latest updates
onto Patriot 4gb flash drives

This bug occurs consistently at two points during the process:

1. durign the start of the copy process
2. During the "system policy requires authentification for installation of bootloader" prompt (where you need to enter your password to finish the process)

It's not a huge deal -- it seems to just cause compiz to crash.  Here's
my dmesg from the time I plugged into the flash drive through the entire
process:

Ubuntu seems to recover more-or-less gracefully, and it doesn't *seem*
to affect the performance of the flash drive.  If others can verify,
then it might make sense to leave it "as-is" or with a brief popup
window on startup that informs the user of the bug and that it is
largely a cosmetic issue.
