[Problem]
Several users are reporting an X crash with a backtrace like this one.  It
seems to happen in relation to firefox usage.  This one occurred when using
AOL, another sees it when typing 5-6 characters slowly in the firefox search
bar.

[Original Description]
Was entering data on AOL mail when Lucid crashed and login screen came up.
