Is that the only file consistently corrupted or are there others? I've seen similar "mysteries" before that turned out to be a memory issue, once system memory, once CPU cache (that was really weird). I'm not sure this is a memory problem, but wouldn't hurt to run a memory test.
It's the only consistency corruption, other files are left intact. Gived it a chance to show troubles: left it last night with memtest86 running. Went smoothly without errors till morning. Now I'm proceeding with a full reinstall, will look what will it give to me in the end ;).
