What steps will reproduce the problem?
1. Mousing over players with buffs (not all buffs cause this error, see below)
2. Targeting players with buffs
3. Being buffed myself

What is the expected output? What do you see instead?
TrainingWhells should work properly with all different kind of buffs. Instead it produces an error message when confronted with some buffs. The message keeps reappearing for as long as the buffs are active and the spell list TrainingWheels creates doesn't show up during that time.

What version of the product are you using?
r52693.81

Do you have an error log of what happened?
I don't know where to find the error log. But the error message I get reads: "Interface\AddOns\TrainingWheels\TrainingWheels.lua:2454: bad argument #1 to 'min' (number expected, got string)"

Please provide any additional information below.
I did a few checks of when the error message appears and I got the impression that it only happens with buffs that have a timer.
Buffs that produce the error:
1.Everything my level 28 pala can cast on players except the auras. (Even the bubble, seals, 'righteous fury' etc.)
2. Warlock: Only some of the short buffs warlocks get when a talent is activated seem to produce the error (not 'fel armor' and 'demon armor').
Affliction: The error occurs with 'shadow trance' (talent 'nightfall') but not with 'eradication'.
Destruction: 'Master of shadows' (talent 'improved shadow bolt') produces the error. Also one of the talents 'molten core' and 'backdraft' produced the error while the other didn't. (I'm pretty sorry but I forgot which way around it was. I'll update this when I notice it again.)
3. For the spells from other classes I couldn't tell for sure which ones are responsible. I noticed the error with the druid buff, mage buffs, priest buffs and the short buffs of warriors.

I hope this information is helpful. If you need to know anything else please feel free to ask. I'll do my best to get this addon working again, since I really want to be able to use it again.
