Why can't view my friend's profile? (not blocked)?

[oops!]

It's actually my girlfriend's profile and it's been a little over a week now. I know I'm not blocked because she showed me her block list and restricted access list from her profile and I'm not on either. All her other friends can see her profile fine, but her name will not come up when I search for her and when I go to our message conversation I cannot click her name. She messaged me and they're not coming up from my profile. I've tried reporting this to facebook and searching for people with similar issues and possible resolutions and have had no luck. We both tried deactivating and reactivating our accounts and nothing changed either times.

Is this some new bug or flaw on facebook?

There is a bitter ex-boyfriend, could this be some kind of hack?

Any ideas or answers would be greatly appreciated!
Also i can still see her profile picture thumbnail by the conversation and see that it changed.
