This is exactly what the guy from Valspar told me about spray cans: The only time you should really warm your paint cans is if they are a good ways below room temp (75-90 degrees F.) because it forces more paint out when it's hot, then it cools and sprays less paint. When the can is warmed up it creates alot more pressure inside which will force the paint out faster, and not give it enough time to "gas out" the propellant before it hits your surface, then it creates bubbles, just like a can of soda being spilled on a table, only the bubbles won't pop.
