'git fast-export' is crashing on the gcc repo

Simply doing something like:

$ git fast-export --all > /dev/null

results in:

fatal: Could not write blob e69de29bb2d1d6434b8b29ae775ad8c2e48c5391

Since this is extremely enlightening, I patched it as follows:

diff --git a/builtin-fast-export.c b/builtin-fast-export.c
index 2136aad..5c7bfe0 100755
--- a/builtin-fast-export.c
+++ b/builtin-fast-export.c

@@ -104,7 +104,8 @@ static void handle_object(const unsigned char *sha1)
 
 	printf("blob\nmark :%d\ndata %lu\n", last_idnum, size);
 	if (fwrite(buf, size, 1, stdout) != 1)
-		die ("Could not write blob %s", sha1_to_hex(sha1));
+		die ("Could not write blob %s: %s",
+		     sha1_to_hex(sha1), strerror(errno));
 	printf("\n");
 
 	show_progress();

And then running it again produced:

fatal: Could not write blob e69de29bb2d1d6434b8b29ae775ad8c2e48c5391: Inappropriate ioctl for device

adding to today's confusion.
