Thanks, Quinn - as always very helpful! My development team, build process and source control is quite simple: I'm the only developer, using only git and Xcode. You're right about the source file being quarantined - that where I removed the extended file attributes.
I'll keep an eye on this: Never had this issues before, even while the file in question was already existing. It just happened approximately two weeks ago, and the last builds were again fine: Maybe just one of these glitches...
