No, from your report it appears to be an issue with the fighter only buffs that they are casting. If you post your info in that thread it may help the devs narrow down the problem and fix it. The fact that you are getting the same error from an item source may well be the key to the whole problem.
Yeah I upgraded to a 2H wand last night and voila, no more message about a "fighter", so it is the buff on the weapon.
The WEAPON IS the "problem", but only if you are a non-fighter class. If you Examine the weapon you are using, you will see "requires fighter", so replacing that weapon is the only way to "fix" it, but it is not a bug.
It's marked as 'fixed internally', so I'd imagine there is a fix coming next patch. Unfortunately that isn't likely to be until at least the 5th of January.
