Looking at the bug it's concerning UDF2, which, IIRC, included 
enhancements for making DVD-RAM disks effectively read/write, Remember 
those DVD recorders they were selling in the early 2000s as a upgrade to 
VHS? The ones that never seemed to work quite right, and then the 
mechanism died one year and one after the warranty expired? Well that's 
the format, not DVD ISOs in general. (There were two competing 
standards, DVD-RAM and DVD-RW).

I'm guessing this was someone trying to recover a TV program from one of 
those disks. I can't think why else you'd have a UDF v2 disk. Most DVD 
are (or were) written in ISO9660 with a second UDF v1.02 directory as an 
extra. So amusing the bug has remained on the system so long, but if I 
understand it correctly, we're talking about a niche format that's long 
gone.
