As far as I can tell - any action.
Crafting, logging, mining, fighting, sitting, spitting, waving.... maybe not those last 3, but you get the picture.

Class-related actions: so basically crafting, fighting, and gathering.
Pretty sure Rikku is correct and Outlaw is not. I did some lvl 10 guildleves today out near Uldah. I walked back to Uldah, without fighting or getting in combat with anything job-related. Sometime after arriving in Uldah, my dagger broke on me.
You know you've been playing too many MMOs when:
You pass a cop and wonder if it 'Agroed' you.
Another car passes you, you attempt to /follow it.
You use your "push to talk" key while talking on the phone. Text-based games
You put a /s before every message you type in an IM (or equivalent / command) (I have done all)
