I did run

  touch lib/*.* src/*.* && git update-index --refresh && git diff-files

a couple dozen times (the "problematic" files where in src/ and lib), but nothing happened. I just re-checked, and the rebase still fails in the same why...

Perhaps I should add some printfs into the git source to figure out what exactly it thinks is not right about those files... i.e. how does it come to the conclusion that I have local changes, exactly. I don't know how Git does that -- does it take the mtime from (l)stat into account? Perhaps problems with my machine's clock could be responsible?

Local (some more details also described in my first email on this thread, but I'll happily provide more data if I can).

Thanks again,
