Well, I probably removed it myself. It's one of my temporary branches IIRC. Perhaps I forgot to do "bisect reset".

That might be the case. I used bisect on this repo a long ago. I'm not sure what actually happened.

Ah. I forgot to say I'm using git 1.4.2.1. My only wish is not a fix (unless it's a trivial fix) but that bisect should explain the situation better and guide people to fix it. I had grepped bisect man page for "seeked tree" and was still clueless.
