While trying to understand why mkisofs -dvd-video creates an image with a VOB file that has a different MD5 sum than the original (reproducible), I wanted to give it another try and create the image from a directory that not only had VIDEO_TS but also AUDIO_TS. Unfortunately I confused the ext3 and loop gnome-terminal windows, and attempted mkdir on the loop-mounted image. Results: mkdir command printed "Segmentation fault" while the bash shell survived. I can't now umount the loop-mounted file and an oops was logged.
