I get those sorts of things all the time, and not just for Xcode.
I'm not sure what's happening to cause the messages, though.
I frequently get messages like this, after system crashes, that trace
to Preferences files in my home directory. When I examine the
offending files, their contents do not appear to be well-formed plist
files, as their names would imply. In fact, their contents appear to
be seriously random garbage, notably without any embedded ASCII or
UTF-8 printable strings at all. My theory is that this is related to
the fact that I use FileVault to protect my home directory:
apparently, as a result of the crash, FileValue has become confused
over whether a given disk block is presently encrypted or decrypted
(so I theorize, at any rate), and so it's presenting me with
ciphertext instead of plaintext. That's my theory, anyway, bolstered
by a very strong conviction that these problems are much less common
when I don't use FileVault, and likewise that the damage inside such
files when FileVault is not in use is less extensive (parts still
seem to make sense, even of other parts are mangled).
In any case, trashing a file under Preferences/ and resetting those
preferences in the affected application has always been one of the
essential skills of Mac-dom.
