#70 crash in itrunc3 after enabling directory indexes (14d4)

Crash (44)
Mr. Codepage

using 1d4.dmg

I created an ext2fs on linux that had directory indexes enabled using the standard mkfs.ext2fs command line utility. After figuring out that directory indexes prevent being able to mount rw. I used tune2fs on linux again to remove directory indexes with

tune2fs -O ^dir_index /dev/sdf1

I then went back to the macbook and plugged in the external usb drive. It mounted normally. I confirmed rw on the terminal using the mount command.

I then opened the ext2fs manager and saw that I could enable directory indexes, so I clicked on the checkbox and immediately I got a kernel panic.
