(i.e. is it ASCII only? Or is it also utf8 characters? Does it have some special characters in it like points, colons, question marks etc) Does it happen only with a single sha1 or can you apply commits on top of that branch and the error condition persists? > > It seems like there could be some sort of weird bug in the checkout or > possibly somehow some corruption in the actual object tree.
