I recently encountered that error when trying to do an interactive
rebase after using filter-branch to remove a file completely in a
repository. I bisected this issue which pointed at this patch. I'm not
sure how it is related as I'm not too familiar with the sequencer code.
I could help in case any specific information is needed. As a first
step, I've posted the output of "strace /mnt/Source//Git/git rebase -i
HEAD~10" below.
