Do you have a download link? Maybe, but Most Likely Not. It's very unlikely that the message is the quilty one since I have often seen it and it has never caused issues.
I doubt it's a quilty one, since the program outputs an infinite number of "Waiting for a read lock on ..." lines after the "fixme:ntdll:NtLockFile I/O completion on lock not implemented yet" line.
This would seem to suggest it's waiting for its I/O completion callback to proceed.
