I like #2; give me an option to choose whether or not refresh the data.

CHANGE.
I deeply understand the trade-off being made here and don't find it 'wrong' to hit the host for the most accurate information. I would, however, use the cache whenever possible: that's the point of having a cache.
If it were my code, I'd ponder a couple of choices:
1) On initial load, refresh the cache with all the files being referred to for the outline. Pro: Cache gets refreshed; a second load will be much faster. Con: It takes time to refresh the cache.
2) Use the (possibly stale) cache but put up a message that the cache was not checked for staleness and that F5 might be advisable. Pro: Fast load. Con: Possibly incorrect outline. Pro: User can choose how to proceed.
3) Create a preference for the Outline View that clearly indicates how to drive this behaviour. Pro: Let the user decide. Con: Another preference to code and understand. Also, a preference is global; sometimes I just don't care about the outline view and I'm OK with the fact that it's stale.
Again, I don't find the current behaviour 'wrong' - it's a trade-off and those decision points invariably disappoint someone.
