As the title implies, there appears to be an error with my bartender. I use Bugsac/Buggrabber, so when I have an error I hear the "Fatality" sound. It appears to happen when there's a proc on one of my spells that causes that spell to glow on the action bar. I'm not at my machine so I can't list the exact error, but will edit to add it later. Anybody else having a similar issue?

Well, after two LFR wings, a couple of heroic dungeons, and half and hour on the target dummy, I could not reproduce the error. Not sure if there's some other variable at play when I get the error, or if it's just my luck.
