[krbdev.mit.edu #8651] kinit -kt KDB: Cannot find/read stored master key

[Greg Hudson via RT]

I tried running the same script (inside "make testrealm", and gwithout 
the env var settings since that's already taken care of) and 
unfortunately couldn't reproduce the issue, with either master or 1.15.

Knowing that it was trying to read the stash file from the unconfigured 
location is interesting; it suggests perhaps an earlier failure to read 
$KRB5_KDC_CONFIG or something.  But I still can't come up with a theory 
as to what the bug might be.
