fatal: internal error in diff-resolve-rename-copy

[Michael J Gruber <git@drmicha.warpmail.net>]

Hi there,

can someone help me with understanding or debugging the following? With
"log -p --stat" I get that strange fatal error. (With GIT_FLUSH=0 it
appears upfront.)

Without "-p --stat" the log is displayed without a fatal error (same 3
commits), but with "-p" or "--stat" (or both) it's fatal.

I suspect the error is out right before the problematic commit, which is
shown with an empty diffstat.

I did this from a subdir, but the same happens from the root of the
worktree.

git show on the last commit "7896762" shows the creation of a binary
blob "Formular_Lehrverpflichtung_SS09.odt", and "show --stat" gives the
expected stat. What problem could log -p --stat have?

Michael
