The fret ends sticking out is a sign that the guitar was not properly humidified.
Failing that...something inherent in that set of wood/how the wood was aged prior to being used.
What is the actual humididty inside the guitar case? Have you measured it with a hygrometer?
Unless you live in a kiln,, taking a guitar from a properly humidified guitar case to a relatively dry environment for a period of time should not dry it out to the point where it cracks.
From Kevin Ryan's web site, re; humidy;

35% isn't optimal...but it isn't a kiln either.
I also agree with his recommendation to use something like the Plant Waves humidifier rather than a plastic bag with holes punched in it.
They are cheap. Less prone to leaking, Seem to humidify longer.
10 or 15$ to protect a multi-thousand dollar guitar correctly seems like a reasonable investment.
