Probably not, if you wrap up your current obligations in a professional manner and can demonstrate that you haven't lost your skills while on your trip.

I strongly agree with this. We're talking about hiring human beings, not machines, and someone with the character traits that would make you go adventuring for an extended period probably has a lot to offer, other things being equal. The challenge is demonstrating that other things have not suffered as a result of that choice.

For example, a good reference from the last employer confirming that everything was professionally handed over before leaving might go a long way to mitigating concerns about only working there for a few months. I'm not generally a big believer in relying on references when hiring, but in a case like this, that sort of specific detail could be an important asset. Given the relatively short professional career so far, I would also be tempted to work a brief mention of this point into the covering letter or, if it's a resume-only application next time, into the resume itself.
